BI only
CII only
DIII only
EI, II, and III
正确答案： D解析：
Since m=n+1, where m and n are given as positive integers, Roman numeral choice I is true. Since, m=n+1, m can be either odd or even, hence choice II is false. Roman numeral choice III is also false since n can be either even or odd. -

DⅠ and Ⅲ only
EⅡ and Ⅲ only
正确答案： D解析：
Since ab3c4is negative and c4 is positive, then in ab3 one variable is positive and the other negative. Hence ab<0, or negative, so Ⅰ is false and Ⅱ is true. Now let’s look at Ⅲ. You know ab is negative — but you don’t know a thing about C. It could be positive or negative. So cross out E.. -

第22题：
单选题For which of the following equations is x = -2 a root?I. 2/x-4II. x2 + 4=0III. x2 + 4x +4 = 0AI only
BII only
CIII only
DI and III
EII and III
正确答案： C解析：
For each Roman numeral equation, check whether -2 is a root.
I. If (2/x)-x = 0, then 2/x =x. If x = -2, then 2/x = 2/-2 = -1 ≠ x. Hence, -2 is not a root of equation I.
II. If x2+4 = 0, then (-2) 2+4 = 4+4≠ 0. Hence,-2 is not a root of equation II.
III. If x2+4x+4 = 0, then (-2) 2+4(-2)+4 = 4-8+2 = 0. Hence, -2 is a root of equation III.
Only equation III has -2 as one of its roots. -
第23题：
单选题A die whose faces are numbered from l to 6 is rolled. Which of the following statements must be true?Ⅰ. The probability of getting a 4 on the top face is 2/3.Ⅱ. The probability of getting an odd number on the top face is 1/2.Ⅲ. The probability of getting a prime number on the top face is 1/2.AⅠand Ⅱ only
BⅡ and Ⅲ only
CⅠ and Ⅲ only
DⅡ only
EⅠ, Ⅱ, and IⅢ
正确答案： E解析：
There are total six different results when the die is rolled. Since any one of the six numbers many show up on the top face, the probability of getting a 4 on the top face is 1/6. Hence, Roman numeral Ⅰ is not true. Statement Ⅱ is true. Since there are three prime numbers, the probability is 3/6 or 1/2. Hence, Roman numeral Ⅲ is true.
