In this excerpt, when Tom says, “You could land a 747 on these two tubes and they’d hold,” he means
A they will stay together under intense pressure.
B they could be used to build aeroplane wheels.
C they have a clean metal frame similar to an aeroplane frame.
D they could withstand an aeroplane crash.
The correct answer is A they will stay together under intense pressure.
In this context, Tom is emphasizing the strength and durability of the “two tubes” by comparing them to something as large and heavy as a 747 airplane. His statement suggests that they are robust enough to support a significant amount of weight or pressure without breaking apart. This comparison underscores the reliability of the materials or structures he is referring to.
