This question seems straightforward, I think the answer is B. Testers are more motivated when their contributions are recognized and they are given increased responsibilities.

I'm a bit confused on this one. I'm not sure if the high site would have a higher or lower transmit frequency. I'll need to review the key principles behind microwave link design.
