1. If a theory is obsolete, what is true of it?

A. Up to date
B. Outdated
C. Innovative
D. Scientific

Correct answer: B

Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

2. It's true that children depend on their parents for food, clothing, and ______.

A. shelter
B. security
C. guidance
D. affection

Correct answer: A

Rationale: Children depend on their parents for providing basic needs like food, clothing, and shelter. 'Shelter' refers to the physical protection and housing that parents are responsible for providing to their children. While security, guidance, and affection are also important aspects of parenting, in the context of the question, the most essential need after food and clothing is shelter.

3. In the address 'Mr. Ryan, 1600 Pennsylvania Ave., Washington, DC 20003,' which word is the salutation?

A. 1600 Pennsylvania Ave.
B. 20003 (Area code)
C. Ryan
D. Mr.

Correct answer: D

Rationale: The correct answer is 'D - Mr.' The salutation is the formal title used before a person's name, which in this case is 'Mr.' Other choices are incorrect as '1600 Pennsylvania Ave.' is the street address, '20003' is the zip code, and 'Ryan' is the recipient's name.

4. What does 'Contour' mean?

A. Flat area
B. Shape or outline of something
C. Volume of a structure
D. Height of a structure

Correct answer: B

Rationale: The term 'Contour' specifically refers to the shape or outline of something. In art and geography, contours are used to represent the outline or shape of an object or landform, making choice B the correct definition. Choice A, 'Flat area,' is incorrect as it does not capture the essence of contour which is about the shape or outline. Choice C, 'Volume of a structure,' is unrelated to the concept of contour. Choice D, 'Height of a structure,' is also incorrect as contour is more about the shape and not the height of an object.

5. It is required that he _____ payment immediately.

A. make
B. sends
C. sent
D. deliver

Correct answer: A

Rationale: The correct answer is 'make.' In this context, 'make' is the correct verb to use with 'payment.' The sentence structure requires a base form of the verb after 'required that.' Choices B, C, and D are incorrect as 'sends,' 'sent,' and 'deliver' do not match the structure needed in this sentence.
