Which piece of evidence would best support this argument?
the brighton bears lost the championship soccer game because they didn't work together as a team.
a. my friend sharon, who attended the game, said that the players were unmotivated and didn't seem to care at all about winning.
b. a 1994 study conducted by national school league usa showed that coaching, rather than teamwork, is the most important factor in determining a team's success.
c. according to the weather report, it was 98 degrees with high humidity on the day of the game.
d. a local newspaper reported that several players admitted they'd had a big argument before the game and had felt the effects of the argument on the field.

D.A local newspaper reported that several players admitted they'd had a big argument before the game and had felt the effects of the argument on the field.

Option D is the most reliable source, as it tells us what the players thought. Not only were they responsible for the outcome, but they have admitted that the team was impacted by an argument before the game.

Option A is hearsay, and it comes from a person who was not directly involved in the game. Option B and Option C, on the other hand, give reasons for the loss (coaching and weather) that do not support the argument.

b is the answer.   i sat on the lumpy sofa, totally exhausted, with a bad taste in my mouth, wondering what i should do next.
