While our parents were working, Mrs. Kent watched <u>us.</u>
they or we, wouldn't make sense when you read the sentence.
Hope this helps.
Hello. You did not present the text to which this question refers, which makes it impossible for it to be answered accurately, but I will try to help you in the best possible way.
1. The mistake of this statement is to use the term "muscular system" and not "locomotor system." This is because the locomotor system is formed by the muscular system and the skeletal system, but people believe that this system is only related to the bones, completely ignoring the function of the muscles. Thus, the correct phrase would be: A common misconception is that the locomotor system moves only the bones.
2. Many people have this misconception because they do not really know the name of the systems, and do not know that the systems can form pairs and groups, which are named differently.
I think the answer could be c or d. D makes a little more sense though. I hope this helps a little bit.
