What is the correct english for this sentence?
i work at my mom and dad's store every evening? or
mom's and dad's
mom and dads
moms and dad's

mom and dad's.

Explanation:  When you need to show possession with a compound noun, use an apostrophe, if both nouns own the same thing, the apostrophe is placed after the last noun. If both nouns possess different things, then an apostrophe must be added to each. In the given sentence, as the store is owned by both (mom and dad) the apostrophe should be placed after the last noun: I work at my mom and dad's store every evening.

faulty parallelism is a construction in which two or more parts of a sentence are equivalent in meaning but not grammatically similar in form.

the correct version of this faulty parallelism in the sentence is:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

the problem is the last sentence, the first two have a basic subject+verb+object structure.

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in all three sentences:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.
