<p>For 7- ‘and that is’ is just too wordy to be correct</p>
<p>For 11- The answer you chose, choice E uses ‘being interrelated,’ which is in the passive voice. ETS renders the passive voice incorrect, for the most part.</p>
<p>the answer for number 21 is ‘E.’
What explanation do you want?

<p>for 7, there’s nothing wrong with ‘that is’ except that it is not necessary.
‘that is’ is refereing to the insurance coverage.
People pay for coverages not premiums. also, the verb is ‘is’, which agrees with the coverage’s singular tense</p>
