In the question given below, a sentence is given with two words missing. You are given five options each containing a pair of words that can or cannot fill the blanks grammatically and /or contextually. Identify the words that are opposite in meaning to each other and make the sentence grammatically and contextually correct. The answer to the question given ____ should be written ____.
I. Above, below
II. High, low
III. Straight, point

The given sentence talks about how the answer to the question given should be written in a specific place. 'Above' means physically over and 'below' means lower in spatial position. The usage of the two words conveys that the answer, to the question given on top, should be written in the space given at the bottom. Hence, (a) is the correct answer. II is also a pair of opposite words but renders the sentence meaningless. III is not a pair of opposite words and doesn't fall in line with the given context. The correct sentence is: The answer to the question given above should be written below.
