Modifier Question: Ask yourself who is "
Responsible for charting the flight paths for sixteen separate airlines" is it 1)
a detailed map 2)
multiple variations or 3)
the flight controllers. It is clear that its
"the flight controllers" so, A, B and E are out. So, its between C & D.
(A)
a detailed map that displayed multiple variations of each plane's trajectory was drawn up by the flight controllers
- Incorrect because of modifier issue as stated above.(B)
a detailed map of each plane's trajectory was drawn up by flight controllers to display multiple variations
- Incorrect because of modifier issue as stated above.(C) the flight controllers,
displaying multiple variations of each course, drew up a detailed map of each plane's trajectory
- Although it fixes one modifier issue but it has another modifier issue (participle/verb+ing form). The flight controllers didn't display the variations, it has to be the map.(D)
the flight controllers drew up a detailed
map that displayed multiple variations of each plane's trajectory
- Modifier issue is fixed. "That" correctly refers to "map" which displays the variations.(E)
multiple variations of each plane's trajectory were displayed on a detailed map drawn up by the flight controllers
- Incorrect because of modifier issue as stated above.Answer: (D).
