Below are sample questions representative of the exercises included on this worksheet and related 4.50 Source Credibility Basics skill assessments:

Problem 1Difficulty: Mastery

Why is Source A more credible than Source B for learning about how to pick a trustworthy website for research?

AIt has more emojis, so it is easier to believe.

BIt is longer, so it must be true.

CIt is online, so it is always newer than social media.

DIt names a responsible author and was recently updated, and it points to reliable places to check the facts.

Solution & Explanation:Credible sources usually tell who created them, give an update date, and show where information can be checked. Social media reposts often leave those details out.
