Question

in 2022, mountain guide phil henderson led the full circle expedition, a team of ______ that became the first all - black team of climbers to summit mt. everest and that works to promote diversity and representation in outdoor adventure sports.
which choice completes the text so that it conforms to the conventions of standard english?
choose 1 answer:
a mountaineers;
b mountaineers and
c mountaineers
d mountaineers,

Explanation:

The text has a non - restrictive relative clause ("that became...outdoor adventure sports") modifying "a team of mountaineers". In Standard English, a non - restrictive relative clause is set off by a comma. Option A uses a semicolon which is incorrect for this context. Option B ("mountaineers and") would make the sentence structure incorrect as there is no proper continuation after "and". Option C has no punctuation to set off the non - restrictive clause. Option D ("mountaineers,") correctly uses a comma to set off the non - restrictive relative clause.

Answer:

D. mountaineers,
