What does 'expand' mean?

Correct Answer: B

Rationale: The correct answer is B. 'Expand' means to increase in size or amount. Choice A, 'To decrease in size,' is the opposite of what 'expand' means. Choice C, 'To spread out,' is related to expanding but does not precisely define the term. Choice D, 'To eliminate,' is not synonymous with the term 'expand.'

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.

Rationale: The correct answer is B: 'To begin or put into practice.' 'Initiate' means to start or commence something. Choice A, 'To finish,' is incorrect because 'Initiate' refers to the beginning of something, not its conclusion. Choice C, 'To delay,' is incorrect as it is the opposite of what 'Initiate' means. Choice D, 'To stop completely,' is also incorrect as it is the opposite of starting or initiating something.

Correct Answer: B

Rationale: Labile means something that changes rapidly and often. In this context, 'Stable' (Choice A) is the opposite of labile, 'Unchanging' (Choice C) and 'Rarely changing' (Choice D) do not capture the essence of labile. Labile is specifically used to describe something that is easily altered, constantly changing, or unstable, hence the most suitable choice is 'Changing rapidly and often' (Choice B).
