Answer:
The visitors to the farm walked through the corn maze, and then they bought a pumpkin.
Explanation:
Firstly, let's see if all the revised sentences make grammatical sense.
1. The visitors to the farm walked through the corn maze, and then they bought a pumpkin.
Sentence one is grammatically correct as it uses and to connect the two clauses.
2. The visitors to the farm walked through the corn maze; bought a pumpkin.
Sentence two is not grammatically correct as it has an unnecessary semi-colon with a dependent clause.
3. The visitors to the farm walked through the corn maze, they bought a pumpkin.
Sentence three does not use and to join the two clauses.
4. The visitors to the farm walked through the corn maze; and then they bought a pumpkin.
Sentence four like sentence two uses an unnecessary semi-colon that does not follow the semi-colon rule.
A semi colon should be used to join two independent clauses or to replace (and, or, but,etc)
Hope it isn't confusing, and it helped! :))
The complete adjective clause in the sentence is F. that I have prepared.
An adjective clause usually starts with who, whom, when, where, why, that or which. Most often it provides more information and description; however, it will not change the meaning of the sentence.
