(A) The Panthers have defeated fewer opponents than the Cougars this year.
---> this is out of scope of the passage so can't be the answer.
(B) Fonsica is the Panther's best defensive player.
---> contradicts what is stated in the paasge, so can't be the answer. We can't assume that coach is lying about the player.
(C) The Panthers' best defensive player will not be defending against the Cougars' highest scoring player.
-- > BINGO, this gives us an alternative fact, that suggests a possibility that of coaches prediction could go wrong.
(D) Fonsica is not the Panthers' best defensive player.
--- > Again, contradics what is stated, we are looking for alternative explantion or fact
(E) The Cougars' highest scoring player will not be defending against Fonsica.
-- > again out of scope of the arguement.
Here stated assumption is that increase in the number of Monrovian immigrants are causing trouble. So, we should look for a fact that states that number is actually decreasing to disprove the stated conclusion.
(A) Each year more violent criminals are apprehended in Abstania than in Monrovia.
--> Out of scope, we don't know whether these criminals are not Monrovians.
(B) During 1998 more violent crimes were reported in Abstania than in Monrovia.
-- > doesn't address the issues
(C) In 1998 no Monrovians migrated from either Monrovia or Abstania to any country other than Monrovia or Abstania.
-- > doesn't addresss the issue
(D) In 1998 the number of unreported violent crimes in Abstania increased as well.
-- > doesn't address the issue
(E) In 1998 fewer Monrovians migrated from Monrovia to Abstania than from Abstania to Monrovia
---> RIGHT. This suggests that more people are in fact leaving Abstania.
Hope this helps.
