"Support" or "Strengthen" does not mean "prove true"

You do not need to find a choice that proves that an argument is true beyond any doubt. If a choice strengthens an argument, even by a minute amount, then it is sufficient. Also, only one choice will actually support the argument. If you ever find yourself with two choices that both seem to support the argument, do not try to weigh which one supports more. Instead, determine which one does nothing to the argument, and is thus incorrect. See LSAT PrepTest 50, Section 4, Question 23.

 

Do not attribute a conclusion to the author that the s/he does not explicitly state or imply.

Do not guess at the author's conclusion -- only work with what is stated or implied. See LSAT PrepTest 50, Section 2, Question 13. The author does not take an extra step and state that the fossil-fuel producers should be forced to to find substitutes to halt global warming. Incorrect choices (A) and (E) attempt to support this claim that the author has not made.

 

EXCEPT Questions

For this type of question, the correct choice does not necessarily need to weaken the argument; it could simply do nothing to the argument.
