Reading the argument
If another crew member can see my adjustment immediately, we have an easy way to check what I've done. Making that adjustment harder to see seems to remove a useful safeguard. Why change the design?
The passage doesn't answer that question. It tells us the consequence instead: crews in newer planes must talk about their changes more often. Where a colleague once could check the panel, I may now need to say what I changed. Verbal updates help fill the gap left by a less convenient visual check.
What we’re looking for
We're asked what the statements most strongly support. We don't have to invent the designers' reason or decide whether the change was wise. I'd expect something connecting the available ways to check flight controls with the need to exchange information verbally. Keep that connection limited to what we were actually told.
Working the answers
- A
How long a change takes is different from how easily another person can observe it. The passage connects verbal communication with visibility of changes, not the time required to perform them. A would need evidence about that separate factor, especially to call it a large influence.
- B
More frequent doesn't mean most valuable. The crew could rely more heavily on verbal updates while another kind of check remained especially valuable. We haven't ranked all available methods. B adds that ranking to the fact that verbal exchanges are needed more often.
- C
Less need for verbal updates in older planes doesn't mean no need. Crew members might still have to tell one another about certain changes or explain them in particular situations. The passage compares how frequently they must communicate; C erases that possibility altogether for the older aircraft.
- D
Harder to observe doesn't mean impossible to observe. A change could still be visible through the panel but require more effort to check. We don't need to know exactly why it is harder to recognize that D turns an increased difficulty into a complete inability.
- ECorrect
The availability of other checks affects how often the crew must communicate verbally. The older panel makes visual checking easy; the newer design makes it harder, and the passage says the crew consequently has to speak more often. E captures that connection while saying only that other checking methods are part of what determines the need for verbal updates.
