Select the most appropriate option to fill in blank number 5.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. “limited.”
The sentence reads:
“The occurrence of landslides can be heightened by human activities, including but not ___ to agriculture and building.”
The phrase “including but not limited to” is a standard expression used to indicate that the listed examples are not exhaustive.
Human activities that contribute to landslides—such as agriculture and construction—are often specifically mentioned, but the phrase implies there are other activities beyond those listed that can also cause landslides.
