In DS, an answer is achieved only when the answer is "consistent".
Q. Is X a multiple of 24?(1) X is a multiple of 6.(2) X is a multiple of 4.
X = 24 satisfies both (1) and (2), leads to "Yes".X = 12 satisfies both (1) and (2), leads to "No"."Inconsistent". Hence, insufficient. Answer is E.
"simple tenses" are the "default tenses".
Other tense forms are meant for specific uses.
