B. Spiral Model
C. Agile Model
D. Layered Model
E. The version of Windows before Vista
2) More software projects have gone awry (failed) because of
A. Lack of manpower
B. Lack of time
C. Lack of funding
D. Lack of good software engineering tools
E. Lack of testing
3) Probably the biggest drawback of the Waterfall Model is
4) What does it mean for a design (say, a class) to have high cohesion?
A. Methods in a class work together on a focused task
B. Methods in a class are grouped together because they are frequently used methods
(object management optimization)
C. Methods in a class are grouped together because they provide the same basic function (like I/O)

C. Multiple classes are not dependent on each other; instead they use a public interface to exchange
parameter-less messages (or events)
D. Multiple classes are coupled by inheritance of implementation low in the inheritance hierarchy
7) Which is considered a good and desirable design?
A. Low cohesion and low coupling
B. Low cohesion and high coupling
