Final answer:
The sentence in question does not have errors requiring correction. However, understanding comma usage and apostrophe application is crucial. Commas are used to separate independent clauses when they are joined by a conjunction, and apostrophes show possession or are used in contractions.
Step-by-step explanation:
When addressing the sentence, "She received her allowance from her father after she completed her chores: mowing the grass, watering the flowers, and feeding the puppy," it appears to not contain overt mistakes that require correction. The sentence succinctly communicates that the subject received her allowance upon completing several tasks and lists those tasks in a series. To assist you further, let's instead review general comma usage and apostrophe application to ensure you can identify errors in similar sentences.
Here are several examples where missing commas need to be inserted or incorrectly placed commas need to be omitted:
I finally found my keys, and I got to work just in time. (A comma is needed before the coordinating conjunction 'and' connecting two independent clauses.)
Mrs. Contreras threw out her old coffee table and cleaned the carpet. (No comma is needed before 'and' because it connects two verbs relating to the same subject without forming separate independent clauses.)
Moreover, it's important to use apostrophes correctly to show possession or to form contractions:
It should be Famer John's land, indicating possession by Farmer John.
One's labor is proportional to one's wealth. Both instances require an apostrophe before the 's' to denote possession by 'one'.
