Question

A. Finding out if her friend has ever taken a biology class
B. Doing a science experiment that involves eggs
C. Determining if the information came from a reliable source
D. Reading books about bird eggs and reptile eggs

Answer 1

The first step in investigating Madison's friend's claim is to C) determine if the information came from a reliable source.

Step-by-step explanation:

A good first step in investigating Madison's friend's claim that the platypus is the only mammal that lays eggs would be to determine if the information came from a reliable source (Option C). This is important because it allows us to verify the accuracy of the claim. By checking reliable sources such as scientific journals, textbooks, or reputable websites, we can gather credible information about mammal reproduction and determine the accuracy of the claim. Option A (Finding out if her friend has ever taken a biology class) may also be helpful in assessing her friend's knowledge, but it does not confirm the accuracy of the claim. Doing a science experiment with eggs (Option B) would not provide conclusive evidence about mammal reproduction, and reading books about bird and reptile eggs (Option D) is not directly relevant to verifying the claim.
