●Question 2. Critical Reasoning
In recent years, many cabinetmakers have been winning acclaim as artists. But since furniture must be useful, cabinetmakers must exercise their craft with an eye to the practical utility of their product. For this reason, cabinetmaking is not art.

A. Some furniture is made to be placed in museums, where it will not be used by anyone.
B. Some cabinetmakers are more concerned than others with the practical utility of the products they produce.
C. Cabinetmakers should be more concerned with the practical utility of their products than they currently are.
D. An object is not an art object if its maker pays attention to the object’s practical utility.
E. Artists are not concerned with the monetary value of their products.
●Question 3. Data Sufficiency
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.
If there are different positive 3 integers and the average (arithmetic mean) is 8, what are the value of the 3 integers?
1) The largest integer is 2times the smallest integer.
2) There is 9 among the 3 integers.
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
●Question 4. Problem Solving
If x^2=x+1, what is x^3, in term of x?
A. x+1 B. x-1 C. 2x-1 D. 2x+1 E. 4x+1
●Answer to Q1: B
In A, the relative clause is awkwardly modifying ‘the park’s development’, not ‘the park’. Meanwhile, ‘open to the public early next year’ is also being misused to modify ‘the park’s development’ in D. And the unidiomatic expression is placed in C in terms of the usage of the verb ‘propose’. In E, ‘that’ as a conjunction is needed in front of the expression and ‘is to be’ should be changed into ‘be’ to make a subjunctive mood in consideration of the verb ‘propose’. So, the answer is B.
●Answer to Q2: D
An assumption plays the role of linking logically the premise to the conclusion in any statement. Accordingly, the conclusion of the statement is depending on an unseen assumption that nothing created with a view to its usefulness is a work of art. In total, the answer choices except for D are irrelevant in terms of mentioning the relationship between art and the practical utility of product.
●Answer to Q3: A
Condition 1) only 5,9,10 can be true, because 6,6,12 are opposite to different 3 integers on the original condition, the best answer is A..
●Answer to Q4: D
x^3=x*x^2=x(x+1)=x^2+x=(x+1)+x=2x+1, therefore the best answer is D.
