   How frequently an airplane’s flight crew members will inform each other verbally about flight control changes depends in large part on how long

   Too Strong: depends in large part Out of Scope: how long to change Nothing in the paragraph talks about how long it takes to make a flight control change (it doesn't even make a lot of sense — aren't we just talking about turning a knob or flipping a switch?)

   Too Strong: most valuable14% picked this

   In recently manufactured aircraft, the most valuable means available for performing cross-checks involves frequent verbal exchanges of information

   This is certainly going in the right gist-y direction, but it's got the poisonously strong word of "most". We don't have any way to rank verbal cross-checks as #1 cross-checking means. The means it replaced was only labeled a routine means for performing cross-checks. The paragraph only told us that cross-checks are valuable. It didn't use any comparative language to rank them.

3. C

   Too Strong: no need8% picked this

   In older commercial airplanes, in contrast to recently manufactured airplanes, flight crew members have no need to exchange information

   We know that in newer planes the flight crew informs each other verbally much more frequently, but that doesn't mean that in older planes the flight crew never informed each other verbally.

4. D

   Too Strong: cannot observe9% picked this

   The flight crew members operating a recently manufactured airplane cannot observe the flight control changes made by other crew members

   The passage tells us that the newer control panel makes flight control changes harder to observe, not impossible to observe.

   How often flight crew members must share information verbally about flight control changes depends in part on what other means for performing

   Why this is right

   This has safer language: depends in part. This just reinforces the Causal Connection conveyed by the "as a result". Because one means of cross-checks was made less available (newer planes make it harder to observe changes on the control panel), flight crew members started to need to share information verbally much more frequently. So we can derive that "the availability of alternative means of cross-checking can have an impact (depends in part on ) on how frequently members need to verbally share information".
