Dear instructors,
I have the following questions:
1) I originally believed that the relative pronoun that referred to the AM-1 satellite.... clearly, I missed the TOUCH RULE. My questions:
What kind of phrase is one of the many new satellites? I wrongly considered this phrase a "mision-critical" modifier.
Moreover, the verb "is" would have indicate that the subject of the relative clause were satellites ?
2)... part of 15 years effort. In this case 15 years functions as an adjective and it should be 15-year effort. My question: This fault is enough to eliminate an answer choice?
Thank you for your comments.
