which sentences are punctuated correctly? check all that apply. they are a happily - married couple. haruko has a part - time job. we watched the quickly moving clouds. elias was well prepared for the exam. a full grown horse is very heavy.
Answer
Brief Explanations:
- "They are a happily - married couple." is correct as compound adjectives before a noun are hyphenated.
- "Haruko has a part - time job." is correct as "part - time" is a compound adjective modifying "job".
- "We watched the quickly moving clouds." is incorrect. Adverbs like "quickly" modifying a present participle ("moving") don't require a hyphen.
- "Elias was well prepared for the exam." is incorrect. "well - prepared" should be hyphenated when used as a compound adjective before a noun.
- "A full grown horse is very heavy." is incorrect. "full - grown" should be hyphenated as a compound adjective before "horse".
Answer:
They are a happily - married couple. Haruko has a part - time job.
