We are given that 35% of Travel Agency Mina’s clientele traveled to Country Rubia and 85% traveled to Country Sol. The key observation here is that the sum of these percentages exceeds 100% (i.e., 35% + 85% = 120%), which suggests that some travelers must have visited both countries.
Now, let’s analyze the answer choices:
(A) Travel to Rubia had fallen for those booking with Agency Mina.
There is no information about past travel trends, so we cannot conclude that travel to Rubia has fallen. Incorrect.
(B) Many people cancelled their bookings.
There is no mention of cancellations in the passage, so we cannot infer this. Incorrect.
(C) Those who went to Country Sol must have enjoyed it more than those that went to Country Rubia.
Enjoyment is not discussed in the given information, so this cannot be concluded. Incorrect.
(D) Some people must have gone to both Country Rubia and Country Sol.
Since the sum of the percentages (120%) is greater than 100%, it must be the case that some travelers were counted in both groups. This means some people must have visited both countries. Correct.
(E) Travel Agency Mina's data must be wrong.
There is no contradiction in the data—having an overlap between travelers explains the numbers. The data does not have to be wrong. Incorrect.
Answer: (D) Some people must have gone to both Country Rubia and Country Sol.
