Heath has found a new online encyclopedia by a company he has never heard of before. heath's friend, sam, urges heath to stick to sites he knows are safe and credible. why is sam so concerned? a. many online references are not regulated c. both of these d. none of these b. online references may contain incorrect information

C. Both of these

It is true that "Online references may contain incorrect information" One of the reasons that incorrect information exists is because "Many online references are not regulated." Wikipedia is often used as an online reference, but since it can be edited by anyone, it can also contain incorrect information. It relies on the users to correct any misinformation as well. The first sentence of the question tells us that there is a possibility for the site to be unreliable.

each year on this day, i make it a point to listen to dr. martin luther king jr.’s great “i have a dream” speech. it’s electrifying every single time.

the content of dr. king’s speech, his inspiring presence, and the moment in history all came together to make the iconic “i have a dream” speech the defining moment of the american civil rights movement. but there are several other reasons why this speech, delivered over 50 years ago, remains an example of one of the best speeches in american history.
