  • B. Measures contributing to cleanliness and good health
  • C. A measure of dietary health

What is a device?

  • A. An idea or concept
  • B. A tool or piece of equipment
  • C. A small part of a larger structure
  • D. An accessory for fashion
Correct Answer: B

Rationale: A device is defined as a tool or piece of equipment designed to serve a specific purpose. It is used to perform a particular function or task. An idea or concept (Choice A) may lead to the creation of a device, but they are not devices themselves. Choice C, referring to a small part of a larger structure, does not encompass the general definition of a device which implies standalone functionality. Choice D, an accessory for fashion, is entirely unrelated to the usual understanding of a device, which focuses on functionality rather than aesthetics.

If a theory is obsolete, what is true of it?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  • B. Outdated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Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant.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D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

The student _____ for the final exam.

  • A. was preparing
  • B. was studying
  • C. had studied
  • D. is studying
Correct Answer: B

Rationale: In the given sentence, the past continuous tense 'was studying' is the most appropriate choice to indicate an ongoing action in the past. 'Was preparing' (choice A) implies a completed action rather than an ongoing one. 'Had studied' (choice C) is past perfect tense, which is not suitable for indicating an ongoing action. 'Is studying' (choice D) is present continuous tense and does not fit the past context of the sentence.

What does Abstain mean?

  • A. To voluntarily refrain from something
  • B. To consume something
  • C. To eat
  • D. To encourage
Correct Answer: A

Rationale: The correct answer is A: 'To voluntarily refrain from something.' Abstain means to choose not to do or have something, especially something you like or enjoy. Choices B, C, and D are incorrect because abstain does not mean to consume something, to eat, or to encourage. It specifically refers to the act of voluntarily refraining from an action or practice.

What is the meaning of NEBULOUS?

  • A. Clear
  • B. Vague
  • C. Precise
  • D. Obvious
Correct Answer: B

Rationale: The correct answer is B, 'Vague.' Nebulous means something that is vague or unclear. Choice A, 'Clear,' is incorrect as it represents the opposite meaning of nebulous. Choice C, 'Precise,' is incorrect as it denotes clarity and exactness, which is the opposite of nebulous. Choice D, 'Obvious,' is also incorrect as it implies something that is easily understood or seen, unlike nebulous which refers to something unclear or hazy.
