### Subject: LSAT

Six violin students—A, B, C, D, E. F, and G—are to give a recital, and their instructor is deciding the order in which they will perform. Each student will play exactly one piece, a violin solo. In deciding the order of performance, the instructor must observe the following restrictions: 1) E cannot play first or second 2) D cannot play until E has played 3) Neither A nor F can play last 4) Either F or G must immediately after D 5) C must play either immediately after or immediately before B plays. If C plays first, which of the following must be true? a) A plays sixth. b) E plays third. c) G plays seventh. d) A plays immediately after F. e) D plays immediately after E.

The correct answer is c). The best way to find the answer to this question is to draw out a list of the potential orders in position number, blocking off when is not available for certain students. Given our rules, we know that E cannot be in position #1 or #2. Because D must only come after E, D may not be in position #1, #2, or #3. Because of this rule, we also know that E cannot be in position #7, since that would preclude D from being included in the lineup. We also know that C and B must be together and cannot be separated. D must come before F or G which again proves that D cannot be in position #7. Since we know that C plays first, we can put C in position number 1. Given our rules, we know that B must then be placed in position #2. Since we have placed both C and B, we take them out of the possibilities for position #7. Thus, since A, F, D, E, C, and B, cannot be in position #7, our only option is G. While we could run through more sequences, the answer has already been made clear. Since no other students may play in the 7th position, G must be in position #7.

### Subject: Basic Math

What is (4+8+10-9)/2?

To solve this equation, we must follow the rules of PEMDAS which stands for parentheses, equals, multiplication, division, addition, and then subtraction. In this instance, we must first start with our equation inside the parentheses before we worry about division. 4 plus 8 is 12, plus 10 is 22, minus 9 is 13. So, therefore, the number inside the parentheses is 13. All we have to do from here is divide 13 by 2. 2 goes into 13 6.5 times, so the answer to this equation is 6.5.

### Subject: Sociology

What are failures or ways that the theory of structural functionalism is short-sighted?

Structural-functionalism theory essentially portrays society as a web of institutions that interact with one another and have interpersonal implications for individuals. While a strong theory, in ways it looks at society solely from a macro-scale perspective, ignoring some of the micro-level interactions which may impact an individual's experience.
