Question

engineers had to evaluate the engines to figure out what went wrong. the engine prototypes that were launched in the test flight had landed in the ocean, as they were supposed to do. so, engineers could not directly examine the engine parts. instead, engineers relied on data that the rocket transmitted, or sent back, to earth during the test flight. engineers examined the temperature data from the part of the rocket that held the j - 2 engines. they noticed an odd temperature pattern that could be explained only if the fuel lines had broken within the first two minutes after launch. so, engineers determined that the engine failures were due to broken fuel lines in the j - 2 engines. the engineers evaluated the j - 2 engines to find the cause of the failure. based on the passage above, which of the following statements about the evaluation of the j - 2 engines are correct? select all that apply. engineers looked only at data from the failed ground tests for clues about why the engines had failed during the launch. engineers analyzed temperature data from the test flight to figure out what went wrong. engineers could not examine the engines used in the test flight to identify the problem because the engines were in the ocean.

Explanation:

The passage states that engineers couldn't directly examine engine parts as they landed in the ocean. Instead, they relied on data transmitted during the test - flight, specifically temperature data from the part of the rocket holding the J - 2 engines. They found an odd temperature pattern indicating broken fuel lines as the cause of engine failures. The first statement is incorrect as they used test - flight data, not ground - test data. The second statement is correct as they analyzed test - flight temperature data. The third statement is correct as the engines being in the ocean prevented direct examination.

Answer:

B. Engineers analyzed temperature data from the test flight to figure out what went wrong.
C. Engineers could not examine the engines used in the test flight to identify the problem because the engines were in the ocean.
