Hello. You forgot to include the excerpt to which the question refers and the answer options.
The excerpt talks about the need to remove mountain goats from the Olympic National Park and transport them to North Cascades National Park.
The response options are:
(4) Once there, helicopters again lifted the goats, this time in crates, into the mountains to be set free.
(5) In this way, wildlife officials caught 114 goats in the first phase of the Mountain Goat Management Plan, but they ultimately will have relocated 90 percent of the 700 goats from the Olympics to the North Cascades.
(6) This removal process may be complicated, but it is necessary.
(9) Since then, the goat population has flourished and could reach 1,500 by 2028.
(10) Park officials also worry about the goats’ deleterious habits of damaging vegetation and causing erosion.
Answer:
(6) This removal process may be complicated, but it is necessary.
Step-by-step explanation:
Although all the answer options somehow express the main theme of the excerpt, the first one that does this is sentence (6), which speaks directly about how the passage of goats from one region to another, although necessary, will not be easy , so it must be discussed and explained in the course of the article, where the other phrases shown will be inserted, thus forming the theme and the main message of the full text.
