Answer 1

The run-on sentence among the given options is: 'Granite has been used for years for paving and building today it's also used for kitchen countertops.'

Step-by-step explanation:

The run-on sentence among the given options is: Granite has been used for years for paving and building today it's also used for kitchen countertops.

A run-on sentence occurs when two or more independent clauses are joined without proper punctuation or conjunctions. In this sentence, there are two independent clauses ('Granite has been used for years for paving and building' and 'today it's also used for kitchen countertops'), but they are not separated by a comma or a conjunction, making it a run-on sentence.

To correct this run-on sentence, a comma or a coordinating conjunction like 'but' or 'and' should be used between the two independent clauses. For example: 'Granite has been used for years for paving and building, but today it's also used for kitchen countertops.'
