1. Identifying errors in sentences
The following sentences test your ability to recognize grammar and usage errors. Each sentence contains either a single error or no error at all. No sentence contains more than one error. The error, if there is one, is underlined and lettered. If the sentence contains an error, select the one underlined part that must be changed to make the sentence correct. If the sentence is correct, select choice E. In choosing answers, follow the requirements of standard written English.

2. Advanced algebra
If x>1 and x =xm, what is the value of m?
(A) -7/2
(B) -3
(C) -5/2
(D) -2
(E) -3/2
1. Correct answer: B. The word “he” should be used because it’s the subject of a sentence.
2. Correct answer: C. Since x can be written as x1/2 and 1/x3 can be written as x-3, the left side of the equation is x1/2 times x-3 = x(1/2 – 3) = x-5/2.
Therefore m = -5/2.
