Answer

Brief Explanations:

The bike - shop owner has a self - interest in promoting his shop. His personal bias can lead to an over - estimation of his shop's services. Option 1 is just a claim made by the owner and doesn't weaken the argument. Option 3 has no indication in the text that the support is outdated. But the bias of the owner in option 2 undermines the objectivity of his statement about his shop having the best tune - ups.

Answer:

  1. A bike - shop owner is likely to be biased in favor of his own shop.
