Samuel is obviously a bad fisherman. During the past season, in which he and the five members of his team spent four months on a boat together off Dutch Harbor, AK, he caught fewer fish than any of his teammates.
Which of the following, if true, most weakens the argument above?

A) Two seasons ago, Samuel fished on another boat off Dutch Harbor and caught more fish than any other member of that boat. --> irrelevant.

B) Before becoming a fisherman, Samuel piloted a fishing boat whose members regularly caught record numbers of fish. --> irrelevant.

C) While fishing this past season, Samuel fell sick for a week and did not catch any fish during this time. --> huh? contender. On second thoughts, a week's sickness should not cause a grave difference and D sounds better.

D) Unlike the other fishermen on his boat, at the order of the captain, Samuel fished this past season with experimental bait --> This differentiates him from others. The experimental bait may be the reason for a lower catch.

E) Amongst the fishing community in Dutch Harbor, Samuel has a reputation for being an especially bad fisherman. --> irrelevant.

IMO (D). Will eagerly wait for the OA.

D again . I go with bad poem's explanation . 1 week is negligible compared 16 weeks( 4 months) . So just because he wasn't well for a week need not necessarily mean that sickness caused him to fish less . In D the use of experimental bait right from the beginning is the one difference between Samuel and other fisher men and this strategy definitely shouldn't have helped him .

D is surely the correct one. As far as C is concerned may be other fishermen were also sick for one week or more no info given. hence D
OA??
