However you are to choose the best answer that is the response that most accurately and completely answers the question. You should not make assumptions that are answer blacken the corresponding space on your answer sheet

5 a2 G* L: E: x& h) K/ ?7 D 1.The painted spiders spins webs that are much stickier than the webs spun by the other species of spiders that share the same habitat. Stickler webs are more efficient at trapping insects that fly into them. Spiders prey on insects by trapping them in their webs therefore. If can be concluded that the painted spider is a more successful predator than its competitors

 Bart: A mathematical problem that defied solution for hundreds of years has finally yielded to a supercomputer. The process by which the supercomputer derived the result is so complex. However, that no one can fully comprehend it. Consequently, the result is unacceptable.

3 P) K* f* x1 l* ? Anne: In scientific research if the results of a test can be replicated in other tests, the results are acceptable even though the way they were derived might not be fully understood. Therefore, if a mathematical result derived by a supercomputer can be reproduced by other supercomputers following the same procedure it is acceptable

  T- g/ Q4 t6 Z( D7 e 5.It is commonly held among marketing experts that in a nonexpanding market a company's best strategy is to go after a bigger share of the market and that the best way to do this is to run comparative advertisements that emphasize weaknesses in the products of rivals. In the stagnant market for food oil, soybean-oil and palm-oil producers did wage a two-year battle with comparative advertisements about the deleterious effect on health of each other's products. These campaigns, however had little effiect on respective market shares; rather they stopped many people from buying any edible oils at all.% d  Z4 z9 P0 _/ j5 @; t
