FREE LUNCH CHALLENGE IS BACK!

Many of you are studying for the SAT or ACT right now.  These are entrance examinations for college.  Students who wish to attend law school are required to take an examination called the LSAT or law school admissions test.  The LSAT is a 4–hour exam that consists of five sections: Analytical Reasoning, Logical Reasoning, Reading Comprehension, an Experimental section and a Writing Sample.  We did a sample logical reasoning question on one of our previous free lunch challenges.  Following is a sample of an analytical reasoning test question like one you might find on the LSAT.  Give it a try for a chance to win today's free lunch challenge:

2. All Labrador retrievers bark a great deal. All Saint Bernards bark infrequently. Each of Rosa’s dogs is a cross between a Labrador retriever and a Saint Bernard.  Therefore, Rosa’s dogs are moderate barkers.

Which one of the following arguments below uses flawed reasoning that most closely resembles the flawed reasoning used in the argument above?

(A) All students who study diligently make good grades. But some students who do not study diligently also make good grades. Jane studies somewhat diligently. Therefore, Jane makes somewhat good grades.

(B) All type A chemicals are extremely toxic to human beings. All type B chemicals are
nontoxic to human beings. This household cleaner is a mixture of a type A chemical and a type B chemical. Therefore, this household cleaner is moderately toxic.

(C) All students at Hanson School live in Green County. All students at Edwards School live in
Winn County. Members of the Perry family attend both Hanson and Edwards. Therefore,
some members of the Perry family live in Green County and some live in Winn County.

(D) All transcriptionists know shorthand. All engineers know calculus. Bob has worked both
as a transcriptionist and as an engineer. Therefore, Bob knows both shorthand and calculus.

(E) All of Kenisha’s dresses are very well made.  All of Connie’s dresses are very badly made.
Half of the dresses in this closet are very well made, and half of them are very badly made. Therefore, half of the dresses in this closet are Kenisha’s and half of them are Connie’s.
