Target question: Is the tallest child in Class A is taller than tallest child in Class B?
Jump to . . .

Statements 1 and 2 COMBINED
There are several scenarios that satisfy BOTH statements. Here are two:
Case a: Class A heights = {1, 50} and Class B heights = {2, 40}. In this case, the answer to the target question is YES, the tallest child in Class A IS taller than tallest child in Class B?
Case b: Class A heights = {1, 50} and Class B heights = {40, 60}. In this case, the answer to the target question is NO, the tallest child in Class A is NOT taller than tallest child in Class B?
Since we cannot answer the target question with certainty, the combined statements are NOT SUFFICIENT

Answer: E
