Question

Keisha was reporting to her class about the benefits of caffeine. She stated that it heightened alertness. She also showed graphs of repeated trials. She got all of her information from an Internet site with an unknown source.

Which best explains the quality of her claim?

Her claim was weak because her sources were unreliable.
Her claim was strong because she used graphs.
Her claim was biased since she probably likes caffeine.
Her claim was not thorough enough.

Answer 1

Her claim was weak because her sources were unreliable — using graphs doesn’t make information credible if the original Internet source has an unknown/uncertain origin.
