For each of the sentences given below, identify which of the two underlined words/phrases is correct:

1. "Tic" refers to a sudden, involuntary muscle twitch, while "tick" can refer to a small parasitic insect or a repetitive clicking sound. Since the sentence describes an involuntary twitch, "tic" is the correct answer.

2. "Peaked" means to reach the highest point, whereas "piqued" means to arouse or stimulate (such as interest or curiosity). Since the sentence refers to arousing interest, "piqued" is the correct choice.

3. "Augur" means to predict or foretell a future outcome (bode well or ill), while "auger" is a tool used for boring holes. Since the sentence refers to predicting something, "augur" is the correct word.

4.   The correct phrase is "throw off the yoke" (not just "throw off yoke"). "Yoke" symbolizes oppression or burden, whereas "yolk" refers to the yellow part of an egg. "Yoke" is the correct choice in this context.

Thus, the answer is option A.
