Question

According to a recent encyclopedia entry about dog breeds, Labrador retrievers come in two specific breeds: English and American. The article cites six studies from several scientific journals about dog breeding showing that males of both breeds usually average 29-41 kg (65-90 lb) in weight, and females usually average 25-32 kg (55-70 lb) in weight. Anna’s female Labrador retriever weighs 38 kg (83 lb). What does Anna’s dog’s weight indicate about the reliability of this source? A)This is still a reliable source because it clearly cites scientific research. B)This is still a reliable source because it is a printed book, not the Internet. C)This is no longer a reliable source because Anna disproved the studies. D)This is no longer a reliable source because Anna’s dog’s weight is in the range for males.

Answer 1

A) This is still a reliable source because it clearly cites scientific research. 

A is the correct answer because of the fact that they did the study over several dogs, feeding them the same amount of food, at the same time. They did everything the same, while Anna didn't for her dog.

Hope this helps.
