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 If a theory is obsolete, what is true of it?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B. Outdated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Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant.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D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.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. What term refers to the description of events in the order of their occurrence?

A. Chronology
B. Notation
C. Documentation
D. Helicon

Correct answer: A

Rationale: The correct answer is 'Chronology,' which specifically means the arrangement of events in the order of their occurrence. 'Notation' refers to a system of symbols or signs used to represent information. 'Documentation' is the process of recording information, while 'Helicon' does not relate to the description of events.

3. What does 'inflamed' mean?

A. Healthy and normal
B. Reddened, swollen, and often tender
C. Discolored but not swollen
D. Hard and stiff

Correct answer: B

Rationale: The term 'inflamed' means being red, swollen, and often tender. It is a common response of the body to injury or infection, involving increased blood flow and immune cell activity. Choice A is incorrect because 'inflamed' does not describe a state of being healthy and normal. Choice C is incorrect as it only mentions discoloration without the characteristic swelling. Choice D is incorrect as 'inflamed' does not imply being hard and stiff.

4. The plastic surgery improved the _______ of her face.

A. Bearing
B. Serenity
C. Contour
D. Cataract

Correct answer: C

Rationale: The correct answer is 'Contour.' In the context of the sentence, 'contour' refers to the shape or outline of her face, which is typically altered or enhanced through plastic surgery. 'Bearing' refers to behavior or posture, not the physical appearance of the face. 'Serenity' means calmness and peacefulness, which is not relevant in the context of plastic surgery improving the appearance of the face. 'Cataract' is a medical condition affecting the eye and is completely unrelated to the context of plastic surgery improving facial appearance.

5. Choose the meaning of the word intact in the following sentence: 'The capsule remains intact even when placed in water.'

A. Viable
B. Operational
C. Tinted
D. Whole

Correct answer: D

Rationale: In this sentence, the word 'intact' is synonymous with 'whole,' meaning that the capsule remains undamaged or complete even when placed in water. Choices A, B, and C are incorrect. 'Viable' means capable of working successfully, 'operational' means in working order, and 'tinted' means slightly colored.
