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