Correct Answer: D
Explanation:
One word from the first part of the sentence seems to be what we need in the blank. The word is �affects�. If we see this then we can choose words that will give the meaning �affect the interpretation�. Obviously the word �impact� fits. (Note that �impact� is used as a verb here not a noun). For the other word we can consider �cloud� and �color�, both of which can be used as verbs. To cloud would imply to obscure and would be negative, whereas to color is not necessarily negative. Hence we are better to take the words �impact� and �color� as they are less restrictive than �cloud�.
