Directions: In this problem, a question is followed by two statements containing certain data. You are to determine whether the data provided by the statements are sufficient to answer the question. Choose the correct answer based upon the statement’s data and your knowledge of mathematics.
X and y are on the number line and x is right of y. Is xy>0?
1) x<2
2) y<0
A. statement 1 alone is sufficient, but statement 2 alone is not sufficient to answer the question
B. statement 2 alone is sufficient, but statement 1 alone is not sufficient to answer the question
C. both statements taken together are sufficient to answer the question, but neither statement alone is sufficient
D. each statement alone is sufficient
E. statements 1 and 2 together are not sufficient, and additional data is needed to answer the question
How many integers are there such that -8<10-x<5?
A. 10 B. 12 C. 13 D. 14 E. 15
———————————————————————
‘Reared apart from each other’ should not modify the subjects in A and B in terms of achieving the logical meaning. In other words, the participle phrase should be connected structurally with ‘identical twins’. In C, ‘that include many idiosyncrasies of behavior’ is misplaced because the relative clause should modify ‘striking similarities’. Also in E, ‘reared apart from each other’ is not in the ideal position to modify ‘identical twins’. So, the answer is D.
If there is no way of determining the effectiveness of teachers, the conclusion that the school can lay off the least effective teachers can’t be justified. All the answer choices except for A are irrelevant in terms of connecting the decision made by the school board with the plan of the school board.
1) & 2) x=1, y=-1 no, x=-1, y=-1 yes, NOT sufficient. Therefore the best answer is E.
