Review the claim and the two pieces of evidence.Chewing gum can improve our alertness and lower our stress level.Evidence A: During a class discussion, a student shared that he chewed gum throughout a recent chemistry test because he heard it would help him stay calm and alert. He believed that he did very well on the test as a result.Evidence B: In a study of forty participants, those who chewed gum while performing stressful tasks had lower levels of anxiety and higher levels of alertness than those not chewing gum.Why is Evidence B stronger than Evidence A?Evidence A does not directly support the claim. It does not discuss whether chewing gum increases alertness and lowers stress.Evidence A does not come from a credible source. It is based on the opinion of one person who is not an expert and has not done research.Submit
