Question

in the weeks after the camp fire devastated parts of paradise, california, a joint team from the u.s. geological survey and fema flew drones and lidar - equipped planes over the burn scar again and again; the goal was to ____ the unstable slopes systematically for future mudslide risk rather than rely on scattered eyewitness accounts of damage.
2 mark for review
which choice completes the text with the most logical and precise word or phrase?
a rebuild
b survey
c insure
d commemorate

Explanation:

To determine the correct word, we analyze the context: the team used drones and planes over the burn scar to assess unstable slopes for mudslide risk. "Rebuild" (A) is about constructing, not assessing. "Insure" (C) is about protection/insurance, irrelevant here. "Commemorate" (D) is about remembering, not related. "Survey" (B) means to examine or assess, which fits the goal of systematically checking the slopes.

Answer:

B. survey
