(1) Seaweed-based fuel could one day power your car. (2) It is more than just an ingredient in a purifying face mask or a sushi roll. (3) According to new research, seaweed has the potential to become an advanced biofuel known as biobutanol. (4) In the past, U.S. scientists have looked to the possibility of algae-based biofuels, but most of these explorations have shied away from kelp and seaweed. (5) One reason why seaweed may not have taken off as a potential fuel source is the fact that it's not a major part of American culture. (6) In contrast, in Asian countries such as Japan, there has been a long history of seaweed in the cuisine. (7) Japanese researchers are much more familiar with it and have spent decades studying its potential uses. (8) A second reason for the U.S. avoidance of seaweed- based biofuel is the country's lack of experience with seaweed farming. (9) The U.S. is no stranger to seaweed harvesting - ✔✔Choice (C) is correct. The new sentence must be a logical and grammatical combination of the existing sentences, which indicate that "Seaweed-based fuel could one day power your car" and that "It" (presumably, seaweed) "is more than just an ingredient in a purifying face mask or a sushi roll." Only (C) properly orders the two claims, first expressing that "Seaweed is more than just an ingredient.. ." and then, following a correct use of a semicolon to join two related independent clauses, narrowing the focus to "seaweed-based fuel." The other choices introduce errors: choice (A) creates a comma splice (two independent clauses joined by only a comma), choice (B) provides an illogical cause-effect statement, and choice (D) contains a vague pronoun ("it"). (1) Seaweed-based fuel could one day power your car. (2)It is more than just an ingredient in a purifying face mask or a sushi roll. (3) According to new research, seaweed has the potential to become an advanced biofuel known as biobutanol. (4) In the past, U.S. scientists have looked to the possibility of algae-based biofuels, but most of these explorations have shied away from kelp and seaweed. (5) One reason why seaweed may not have taken off as a potential fuel source is the fact that it's not a major part of American culture.(6) In contrast, in Asian countries such as Japan, there has been a long history of seaweed in the cuisine. (7) Japanese researchers are much more familiar with it and have spent decades studying its potential uses. (8) A second reason for the U.S. avoidance of seaweed- based biofuel is the country's lack of experience with seaweed farming. (9) The U.S. is no stranger to seaweed harvesting. - ✔✔Choice (B) is correct. The new sentence, "There are a number of possible reasons for this," needs to fit logically and grammatically between two existing sentences. Sentence 4 states that American scientists have "shied away from," or ignored, kelp and seaweed as possible
biofuels. Sentence 5 notes "One reason why seaweed may not have taken off as a fuel source." Later in the passage, sentence 8 provides "A second reason for the U.S. avoidance of seaweed-based biofuel." The new sentence fits logically and grammatically between sentences 4 and 5 because it introduces the reasons for "this" (American scientists' neglect of kelp and seaweed as potential fuel sources)— reasons that are provided in the following sentences. On the contrary, if choices (A), (C), or (D) were chosen as the answer, "this" would refer to other things for which no reasons are given. (1) Seaweed-based fuel could one day power your car. (2)It is more than just an ingredient in a purifying face mask or a sushi roll. (3) According to new research, seaweed has the potential to become an advanced biofuel known as biobutanol. (4) In the past, U.S. scientists have looked to the possibility of algae-based biofuels, but most of these explorations have shied away from kelp and seaweed. (5) One reason why seaweed may not have taken off as a potential fuel source is the fact that it's not a major part of American culture.(6) In contrast, in Asian countries such as Japan, there has been a long history of seaweed in the cuisine. (7) Japanese researchers are much more familiar with it and have spent decades studying its potential uses. (8) A second reason for the U.S. avoidance of seaweed- based biofuel is the country's lack of experience with seaweed farming. (9) The U.S. is no stranger to seaweed harvesting. - ✔✔Choice (A) is correct. The inserted word or phrase must properly link sentence 7 with the sentences that come before it in the passage. Sentences 5 and 6 suggest that unlike the U.S., where seaweed has not been considered a potential fuel source because U.S. scientists are not familiar with it, Japan has "a long history of seaweed in the cuisine." Sentence 7 states that "Japanese researchers are much more familiar with it and have spent decades studying its potential uses." Only the phrase "As a result" properly links sentence 7 with what has come before: in the context of the passage, Japanese scientists' familiarity with seaweed is clearly a result of its history as a food in their culture. Choices (B) and (C) suggest a contrast between sentences 6 and 7 that does not exist, and choice (D) suggests that sentence 7 simply adds more information to sentence 6 rather than showing the proper cause-effect relationship. (1) Seaweed-based fuel could one day power your car. (2)It is more than just an ingredient in a purifying face mask or a sushi roll. (3) According to new research, seaweed has the potential to become an advanced biofuel known as biobutanol. (4) In the past, U.S. scientists have looked to the possibility of algae-based biofuels, but most of these explorations have shied away from kelp and seaweed. (5) One reason why seaweed may not have taken off as a potential fuel source is the fact that it's not a major part of American culture.(6) In contrast, in Asian countries such as Japan, there has been a long history of seaweed in the cuisine. (7) Japanese researchers are much more familiar with it and have spent decades studying its potential uses.
C. everyone is D. they are - ✔✔Choice (B) is correct. It avoids the pronoun agreement errors of the other options by providing the second-person pronoun "you" to be consistent with the second-person pronoun "your" that follows it ("in your life"). The third-person pronouns "one," "everyone" and "they," in choices (A), (C) and (D), respectively, are not consistent with the second-person pronoun "your." In the Roman Empire, the first fish to be brought indoors was the (sea barbel), it was kept under guest beds in small tanks made of marble. A. sea barbel, it B. sea barbel, which C. sea barbel, but D. sea barbel and - ✔✔Choice (B) is correct. It avoids the comma-splice error of the original sentence by replacing the pronoun "it" with the relative pronoun "which," thus making the second independent clause into a dependent clause. Two independent clauses ("the first fish to be brought indoors was the sea barbel" and "it was kept under guest beds in small tanks made of marble") cannot be joined by only a comma. Choice (C) is incorrect, because there is no contrast between the idea that "the first fish to be brought indoors was the sea barbel" and the fact that the sea barbel "was kept under guest beds." Choice (D) results in awkward phrasing: "... the first fish to be brought indoors was the sea barbel and was kept under guest beds... " The idea that lightning never strikes the same place twice is one of the oldest and most well-known weather-related myths; (in fact), lightning strikes the Empire State Building in New York City about 100 times per year. A. in fact B. therefore C. moreover D. in contrast - ✔✔Choice (A) is correct. It avoids the illogical phrasing of the other options by providing the phrase "in fact," which is used in this context to introduce evidence validating a previous statement. In this sentence, the information in the second clause ("lightning strikes the Empire State Building
... about 100 times per year") offers evidence confirming the truth of the statement made in the first clause ("The idea that lightning never strikes the same place twice" is a "well-known" yet false belief). Options (B), (C) and (D), while grammatically correct, result in illogical phrasing because they do not indicate the relationship specified by the information in the sentence. Horror films (that keep viewers in a state of endless fright and which draw) record-breaking crowds.
A. that keep viewers in a state of endless fright and which draw B. keep viewers in a state of endless fright and drawing C. that keep viewers in a state of endless fright draw D. that keep viewers in a state of endless fright and they draw - ✔✔Choice (C) is correct. It avoids the sentence-fragment error of the original sentence by providing the main verb "draw" to agree with the subject "horror films" and to carry out the action of the sentence. In addition, choice (C) appropriately provides the relative clause "that keep viewers in a state of endless fright" to modify the noun phrase that precedes it, "horror films." None of the other options results in a complete sentence. According to explorers, a "Lost Falls" resembling New York's Niagara Falls (have been found) in Tsangpo River Gorge in the Himalaya Mountains. A. have been found B. has been found C. having been found D. being found - ✔✔Choice (B) is correct. It avoids the subject-verb agreement error of the original sentence by providing the singular verb phrase "has been found" to carry out the action of the sentence. Choices (C) and (D) result in sentence fragments; they provide participial verb forms ("having been found," "being found"), not main verbs. {Think about how you would rewrite the following sentence according to the directions given, and then choose the best answer. Keep in mind that your revision should not change the meaning of the original sentence.} In some places, virtually all the topsoil has washed away, leaving the subsoils to sustain the crops. (Rewrite, beginning with) In some places, the subsoils must sustain the crops ... (The next word will be) A. although B. because C. until D. before - ✔✔Choice (B) is correct. The sentence should be rewritten "In some places, the subsoils must sustain the crops because virtually all the topsoil has washed away." Choice (B) avoids the errors of the other options and appropriately provides the causal link needed to explain why the subsoils must
D. two librarians were - ✔✔Choice (B) is correct. The sentence should be rewritten "Funding for the library was cut by 50%, forcing the director to lay off two librarians and sharply reduce hours of operation." Each of the other choices results in a comma splice, with two independent clauses improperly joined by only a comma. Choice (B) avoids the comma-splice error by providing the participial phrase "forcing the director to lay off two librarians... " to join the independent clause "Funding for the library was cut by 50%." {Think about how you would rewrite the following sentence according to the directions given, and then choose the best answer. Keep in mind that your revision should not change the meaning of the original sentence.} Carmen created a new piñata by constructing a papier-mâché figure and decorating it with brilliantly colored tissue paper. (Rewrite, beginning with) To create a new piñata, ... (The next words will be) A. Carmen constructed a papier-mâché figure B. Carmen, constructing a papier-mâché figure C. a papier-mâché figure that Carmen had to construct D. that Carmen would construct a papier-mâché figure for - ✔✔Choice (A) is correct. The sentence should be rewritten "To create a new piñata, Carmen constructed a papier-mâché figure and decorated it with brilliantly colored tissue paper." Choice (A) avoids the errors of the other options by providing the past tense verb "constructed" to serve as one of the two main verbs in the sentence. Each of the other options results in a sentence fragment with no main verb to carry out the action of the sentence. {Think about how you would rewrite the following sentence according to the directions given, and then choose the best answer. Keep in mind that your revision should not change the meaning of the original sentence.} If Antarctica's icebergs could be floated north before melting, many arid areas would experience relief from drought. (Rewrite, beginning with) If they could be floated north before melting, ... (The next words will be) A. relief would be brought B. many arid areas would experience
C. Antarctica's icebergs would bring D. drought relief would be experienced - ✔✔Choice (C) is correct. The sentence should be rewritten "If they could be floated north before melting, Antarctica's icebergs would bring many arid areas relief from drought." Choice (C) avoids the modification and pronoun errors of the other options by providing the appropriate subject, "Antarctica's icebergs," immediately after the dependent clause that modifies it, "If they could be floated north before melting." Choices (A) and (D) do not clearly establish that "they" refers to "Antarctica's icebergs," and choice (B) illogically implies that "many arid areas" "could be floated north before melting."
