1. When you push a book across a table, the book experiences an equal and opposite force from the table. Why doesn't the table move as well?

• A. The table is much heavier than the book.
• B. The force on the book acts in a different direction.
• C. The table has a much larger surface area, distributing the force over a wider area.
• D. All of the above

Correct answer: A

Rationale: The table is much heavier than the book, so it requires a much larger force to accelerate it. The book is lighter and easier to move, so the force applied to it causes it to move without significantly affecting the table due to the table's greater mass. Newton's third law states that for every action, there is an equal and opposite reaction. In this case, the force exerted on the book by the table is countered by an equal force exerted on the table by the book, but the table's greater mass resists movement. Choice B is incorrect because the forces are equal and opposite, acting in the same direction. Choice C is incorrect as the surface area does not affect the movement of the table in this scenario. Therefore, the correct answer is A, as the table's greater mass prevents it from moving easily when a force is applied.

2. If you go to the market, please pick up some beef, carrots, and celery, and I will make some of that delicious stew we had last week. Which comma should be removed in the sentence above?

• A. The comma after the word 'market'
• B. The comma after the word 'beef'
• C. The comma after the word 'celery'
• D. The comma after the word 'delicious'

Correct answer: D

Rationale: The comma after 'delicious' is unnecessary as it separates the adjective 'delicious' from the noun 'stew'. In this case, 'delicious' is describing the type of stew, so the comma should be removed to maintain correct sentence structure. The other commas in the sentence are correctly used to separate items in a list and after introductory phrases, making them necessary for clarity and grammatical correctness.

3. When a person pushes a box across the floor, which of the following forces is NOT doing work?

• A. The person's pushing force
• B. The normal force from the floor
• C. The gravitational force on the box
• D. The frictional force between the box and the floor

Correct answer: B

Rationale: The normal force from the floor is perpendicular to the direction of motion of the box, so it does not contribute to the work being done. Work is only done by forces acting in the direction of motion of an object. In this case, the normal force is acting at a right angle to the motion, hence it does not perform any work on the box. The person's pushing force, the gravitational force, and the frictional force are all acting in the direction of motion of the box, so they contribute to the work being done in moving the box across the floor.

4. What is 0.04 liters converted to milliliters?

• A. 40 ml
• B. 4 ml
• C. 400 ml
• D. 0.4 ml

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. So, to convert 0.04 liters to milliliters, you would multiply 0.04 by 1,000, giving you 40 milliliters. This means that choice A, '40 ml', is the correct answer. Choices B, C, and D are incorrect because they do not correctly convert liters to milliliters. Choice B, '4 ml', is incorrect as it is 10 times smaller than the correct conversion. Choice C, '400 ml', is incorrect as it is 10 times larger than the correct conversion. Choice D, '0.4 ml', is incorrect as it is one-tenth of the correct conversion.

5. Why does Bobo, despite coulrophobia, book more shows and make more money than Gob?

• A. Bobo is an experienced clown.
• B. Despite rampant coulrophobia, statistical data shows that people generally prefer clowns to magicians for children's birthday parties.
• C. Bobo goes out of his way to appear non-threatening.
• D. Bobo works in a densely populated city, while Gob works in a rural town.

Correct answer: B

Rationale: The correct answer is B because despite the widespread fear of clowns (coulrophobia), statistical data indicates that people typically favor clowns over magicians for children's birthday parties. This preference results in Bobo booking more shows and earning more money than Gob. Choice A is incorrect because being an experienced clown alone does not address the paradox. Choice C is incorrect as the statement does not directly relate to the preference for clowns over magicians. Choice D is irrelevant to the paradox as the location of their work does not explain why Bobo is more successful despite coulrophobia.
