Read the following source listing for research on the topic of fracking:

url: lookingfortruth. com

title: fracking will ruin our environment

author: james johnson, founder of the end fracking now campaign

date: 2013

which is the best evaluation of the source's credibility?

a. the source is reliable because james johnson founded the campaign.
b. the source is transparent so you can trust its information to be true.
c. the source is biased because of its association with a campaign.
d. the source is published recently so it will provide the most accurate information.

the source is biased because of its association with a campaign.

The right answer is the C) The source is biased because of its association with a campaign.

Explanation: Just to elaborate a little on the answer it can be added that, since the same person who wrote the source - an article about the harmful effect of fracking in the environment - also founded a campaign against fracking, and the research is on the topic of fracking (presumably on its pros and cons), it can certainly be inferred that the source will be biased, subjective and partial, since the author has publicly campaigned against fracking.    

i believe it is d.) previous creature

what are the options?
