Craft and Structure practice question

Beachgrass spreads underground stems through loose sand, and its dense roots ____ the dunes, keeping them from washing away during winter storms.

Which choice completes the text with the most logical and precise word or phrase?

  1. A. anchorCorrect
  2. B. decorate
  3. C. confuse
  4. D. replace

Answer: A. anchor

The sentence says the roots keep dunes from washing away in storms — they hold the sand in place, so 'anchor' fits.

Why the other answers are wrong

B. decorate
'Decorate' is about appearance; the sentence is about holding sand against storms.
C. confuse
'Confuse' cannot apply to sand being held in place.
D. replace
The grass holds the dunes; it does not take their place.
