Question

At their summer camp, the Boy Scouts will learn how to set up a tent, digging a latrine, and, under adult supervision, how to build a fire.

Which underlined part of the sentence, if any, contains an error?
A.
how to set up
B.
No error
C.
under adult supervision
D.
digging a latrine

Answer 1

D. "digging a latrine" — the list lacks parallel structure. It should match the infinitive form (e.g., "how to dig a latrine") or make all items gerunds ("setting up a tent, digging a latrine, and building a fire").
