Parasitic wasps lay their eggs directly into the eggs of various host insects in exactly the right numbers for any suitable size of host egg. If they laid too many eggs in a host egg, the developing wasp larvae would compete with each other to the death for nutrients and space. If too few eggs were laid, portions of the host egg would decay, killing the wasp larvae.
Which of the following conclusions can properly be drawn from the information above? (A) The size of the smallest host egg that a wasp could theoretically parasitize can be determined from the wasp’s egg-laying behavior. (B) Host insects lack any effective defenses against the form of predation practiced by parasitic wasps. (C) Parasitic wasps learn from experience how many eggs to lay into the eggs of different host species. (D) Failure to lay enough eggs would lead to the death of the developing wasp larvae more quickly than would laying too many eggs. (E) Parasitic wasps use visual clues to calculate the size of a host egg. 这个选A 求逻辑分析。。。
19. Industrialists from the country Distopia were accused of promoting the Distopian intervention in the Arcadian civil war merely to insure that the industrialists' facilities in Arcadia made substantial
profits during the war. Yet this cannot be the motive since, as the Distopians foresaw, Distopia's federal expenses for the intervention were eight billion dollars, whereas, during the war, profits from the Distopian industrialists’ facilities in Arcadia totaled only four billion dollars.
Which of the following, if true, exposes a serious flaw in the argument made in the second sentence above?
(A) During the Arcadian war, many Distopian industrialists with facilities located in Arcadia experienced a significant rise in productivity in their facilities located in Distopia (B) The largest proportion of Distopia's federal expenses is borne by those who receive no significant industrial profits. (C) Most Distopian industrialists' facilities located in Arcadia are expected to maintain the level of profits they achieved during the war. (D) Distopian industrialists' facilities in Arcadia made substantial profits before the events that triggered the civil war. (E) Many Distopians expressed concern over the suffering that Arcadians underwent during the civil war. 这个选B 没看懂B的意思 也没看懂逻辑意思。。。
