Studies: With the word "who" it proves that that one to be incorrect

B. It is questionable that the sponsor is a broadband internet provider because this sponsor can be greatly affected by the conclusion.
From this research, the increase in grades of subjects could have been due to materials or other journals accessed on the internet rather than the usage of internet. Because if appropriate materials were not accessed by subjects on the internet, probably the increase would not have been achieved.
Thus, the conclusion of the study could have been influenced by the internet provider so as to encourage subjects to believe that using the internet increases grade. This would then increase exponentially the number of subjects that would subscribe to his services.
C. The magazine has an interest in the survey results, so the source of the survey is questionable.
What is wrong is that the magazine has an interest in the survey results, so the source of the survey is questionable. The magazine is not a reliable source because it is biased. When the source is questionable, the survey results are under suspicion. There is a lack of transparency so the results are not credible. The survey is unreliable.
I would say that this is right. If the person decided to send their money to a person who needed it then that alone is a wonderful thing to do. As for the fact that the sender did not include his/her name, they might not want recognition or praise for their actions. Many people decide to donate anonymously because they want to help the cause without getting involved personally.
Hope this helps!
