1. What is the meaning of plastic?
- A. Mechanical
- B. Durable
- C. Authentic
- D. Flexible
Correct answer: D
Rationale: The correct answer is D: Flexible. Plastic is a material that can be easily molded or shaped, known for its flexibility. It can bend and stretch without breaking, making it versatile and durable. Choices A, B, and C are incorrect because plastic is not primarily associated with being mechanical, authentic, or durable, but rather with its ability to be shaped and its flexibility.
2. If a theory is obsolete, what is true of it?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- B. Outdated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Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant.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D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.
3. Which word is NOT CORRECT? The student did not recognize which backpack was hers.
- A. Backpack
- B. Student
- C. Hers
- D. Recognize
Correct answer: C
Rationale: The correct answer is 'C: Hers.' The possessive pronoun 'hers' does not require an apostrophe. The use of 'her's' with an apostrophe is grammatically incorrect. Choices A, B, and D ('Backpack,' 'Student,' and 'Recognize') are all spelled correctly and are grammatically sound in the sentence provided.
4. What is another word for putrefy?
- A. Discharge
- B. Harden
- C. Panic
- D. Rot
Correct answer: D
Rationale: Another word for putrefy is 'rot.' Putrefy means to decay or decompose, especially through the action of bacteria. Similarly, rot refers to the process of decaying or decomposing, making it a synonymous term in this context. Choices A, B, and C are incorrect. 'Discharge' means to release or let out, 'harden' means to make or become hard, and 'panic' refers to sudden uncontrollable fear or anxiety, none of which are synonymous with putrefy.
5. What is the best description of the word 'insidious'?
- A. stealthy
- B. deadly
- C. collapsed
- D. new
Correct answer: A
Rationale: The correct answer is A: 'stealthy.' 'Insidious' is often used to describe something that proceeds in a gradual, subtle, but harmful way. It is not directly or openly harmful like 'deadly,' nor does it mean 'collapsed' or 'new.' Therefore, 'stealthy' best captures the meaning of 'insidious.'
