Hello, on both the tablet and the computer, I'm getting an error saying just "1" on problem sets.
Here are some links: https://classic.7sage.com/lesson/introduction-to-reading-comprehension-problem-set-9/
the other sets are doing the same thing for me. Please advise, thank you.
Omg. I thought for some reason what they meant by “excrete” was that it was excreting out of their BONES and INTO THEIR BLOOD STREAM, so the teenagers who drank more was getting even MORE calcium. SMFH, I’m a dummy.
