According to Albert Einstein’s famous theory of relativity, time travel is theoretically possible.

Q. The argument above makes which of the following assumptions?
(A) It is not possible to alter a significant current in world history merely by changing a single event
(B) The technology necessary for time travel is likely to be developed in the near future
(C) If Franz Ferdinand had not been assassinated, some other catalytic event would have led to the start of World War I
(D) The assassination of Franz Ferdinand was the crucial event that triggered the start of Word War I

The answer is: (D)
