Errors in EK Study materials

Hopefully, this thread will get some good participation.
In the 1001 Biology book, anyone else get more than 1 right anwser to question #883? I think they meant to ask which of the following IS found in Hyaline cartilage.

I don’t have the 1001 in bio. Just in Ochem & Verbal and the mini-mcat book, so yell if you have q’s on those & we can work through those together.
