5. were

5 ?

Nope.

hummmm...maybe i had to much rest :-o

let me see

is it 2 Sue?

No, it's not 2. The subject, "one," is singular.

The best way to write the underlined portion of this sentence is option 2: "have been."

To determine the correct choice, we need to look at the subject of the sentence. In this case, the subject is "approaches," which is plural. Since the subject is plural, we need to use the plural form of the verb "to have," which is "have been." Option 2 correctly matches the plural subject with the plural verb, making it the best choice.
