Rationale: The correct meaning of the word 'Augment' is 'to add to something.'

Correct Answer: B

Rationale: The correct answer is B: 'A deficiency or lack of something.' The term 'deficit' refers to a shortage or inadequacy of something.

Choice C is incorrect as an abundance signifies a large quantity or more than enough of something.
Choice D is incorrect as a stable amount does not convey the concept of a deficit.

Correct Answer: B

Rationale: The correct answer is B, 'Wide open'. Gaping refers to something being wide open, not partially closed (choice

D). In the context of the question, 'Gaping' describes something that is open widely.

Correct Answer: B

Rationale: Collusion refers to a secret agreement or conspiracy, often for deceitful or illegal purposes. While choices A, C, and D may involve some level of agreement or understanding, collusion specifically implies a secretive and usually dishonest arrangement, making choices A, C, and D incorrect in this context.

D) means far on or ahead in development or progress.
Therefore, 'Outdated' is the most appropriate antonym for 'Obsolete.'
