  1. obscured

  2. contradictory

  3. interrelated

  4. enclosed

  5. permeated









The sentence states that MTV, which is “devoted primarily to music,” covered a “presidential race,” which is an example of politics. This implies that politics and music are “interrelated,” or connected.

Of 5 employees, 3 are to be assigned an office and 2 are to be assigned a cubicle. If 3 of the employees are men and 2 are women, and if those assigned an office are to be chosen at random, what is the probability that the offices will be assigned to 2 of the men and 1 of the women?



  1. 1 over 3

  2. 2 over 5

  3. 1 over 2

  4. 3 over 5

  5. 2 over 3






Of the 5 office workers, 3 are to be assigned an office. This is an example of combinations: to find the number of ways of choosing 3 of the 5 workers, you can count the number of ways of selecting the workers one at a time and then divide by the number of times each group of 3 workers will be repeated.

There are 5 ways of choosing the first worker to get an office. Then there will be 4 ways of choosing the second worker to get an office, and 3 ways of choosing the third worker. This is a total of 5 × 4 × 3 = 60 possibilities. In these 60 possible selections, each distinct group of 3 workers will occur 3 × 2 × 1 = 6 times. (There are 3 possibilities for the first worker chosen from the group, 2 for the second worker chosen, and only 1 for the third.) Therefore, there are = 10 different ways the 3 workers who get an office can be chosen from the 5 workers.

How many of these 10 possible groups of 3 workers consist of 2 men and 1 woman? From the 3 male workers, 2 can be chosen in 3 different ways. There are 2 possibilities for the female worker. Therefore, 3 × 2 = 6 of the groups of 3 workers consist of 2 men and 1 woman.

Since there are 10 different ways the 3 workers who get an office can be chosen, and 6 of these possible groups of 3 workers consist of 2 men and 1 woman, the probability that the offices will be assigned to 2 men and 1 woman is , or .

Like machinery was integral to the development of industrial capitalism, so the rapid transfer of information is the force driving modern business.



  1. Like

  2. Given that

  3. Since

  4. Just as

Choice (4) is correct. It avoids the error of the original by providing the appropriate phrase “Just as” to complete the comparison (“Just as machinery … so the rapid transfer of information”).

Woody Guthrie wrote and adapted more than a thousand songs, many of them are about the struggles of workers and the poor in the United States.

  2. many of which are

  3. many are

  4. which are, many of them,

  5. and many of them that are









Choice (2) is correct. It avoids the comma-splice error of the original by using the pronoun “which” in place of the pronoun “them,” thereby turning what was originally an independent clause (“many of them are … United States”) into a relative clause that modifies “songs.”

Read the following SAT test question, then click on a button to select your answer.


A 25-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on concrete 7 feet from the base of the building. If the top of the ladder slips down 4 feet, then the bottom of the ladder will slide out



  1. 4 feet

  2. 5 feet

  3. 6 feet

  4. 7 feet

  5. 8 feet

















The ladder, the wall, and the ground form a right triangle with a 25-foot hypotenuse. At first, the bottom of the ladder is 7 feet from the base of the building, so one leg of the right triangle measures 7 feet; the length of the other leg, x, can be found by solving 72 + x2 = 252, which is the Pythagorean theorem. From this, you can figure out that the other leg measures 24 feet.



After the ladder slips down 4 feet, the 24-foot leg of the right triangle becomes 20 feet long. The other leg then has to be 15 feet long. This length is found by solving 202 + y2 = 252, which is again the Pythagorean theorem.



Since the distance between the bottom of the ladder and the base of the building increases from 7 feet to 15 feet, the amount that the bottom of the ladder slides out is 8 feet.

    Every student who studies art in a certain school receives exactly one of the grades A, B, C, or D. If 1 over 5 of the students receive A’s, 1 over 4 receive B’s, 1 over 2 receive C’s, and 10 students receive D’s, how many students in the school study art?



    1. 30

    2. 60

    3. 100

    4. 200

    5. 500






    The students who receive A’s, B’s, and C’s account for 1 over 5 + 1 over 4 + 1 over 2 of the students, that is,  19 over 20. This leaves  1 over 20 of the students receiving D’s. You know that 10 students receive D’s, so 10 is 1 over 20 of the total. This means that the total number of students is 10 times 20, or 200.

    The stopping distance of a car is the number of feet that the car travels after the driver starts applying the brakes. The stopping distance of a certain car is directly proportional to the square of the speed of the car, in miles per hour, at the time the brakes are first applied. If the car’s stopping distance for an initial speed of 20 miles per hour is 17 feet, what is its stopping distance for an initial speed of 40 miles per hour?



    1. 34 feet

    2. 51 feet

    3. 60 feet

    4. 68 feet

    5. 85 feet





















  • The stopping distance is directly proportional to the square of the initial speed of the car. If s represents the initial speed of the car, in miles per hour, and d represents the stopping distance, you have that the stopping distance is a function of s and that
    d(s) = cs2, where c is a constant. Since the car’s stopping distance is 17 feet for an initial speed of 20 miles per hour, you know that 17 = c(202). Therefore,
    c = 17 over (20 squared) = 0.0425, and the car's stopping distance for an initial speed of 40 miles per hour is (0.0425)(402) = 68 feet.

The word “such” indicates that the second missing term will contrast with “sophisticated.” Only “evolved . . a quaint” satisfies both requirements.

      In the question, you are told that 7 gallons of gasoline can plow 3 acres and you are asked to find how many acres, call it x, can be plowed by 16 gallons. You can set up a ratio of the number of gallons of gasoline used to the number of acres plowed. Therefore, you have 7 over 3 = 16 over x. Cross-multiplying and solving for x gives you the answer of x = 48 over 7 acres, or 66 over 7 acres.

    Choice (B) is correct. If this term were inserted into the sentence, the sentence would read “Mr. Warmington considered himself a connoisseur of fine wines, claiming he could discern variations in taste and quality among any range of vintages he was served.” A “connoisseur” has a sophisticated ability to appreciate and assess subtleties. If Mr. Warmington considered himself a connoisseur of wine, he would claim an ability to “discern,” or detect, variations in the taste and quality of different wines.
