Target question: What is the distance between City A and City C ?

Scan the statements and head straight to . . .

Statements 1 and 2 combined

Case a:

In this case, the answer to the target question is the distance from A to C is 210 km



Case b:

In this case, the answer to the target question is the distance from A to C is less than 210 km

Since we cannot answer the target question with certainty, the combined statements are NOT SUFFICIENT

Answer: E
