This follows from the basicity of the amine. If only one equivalent of acetic anhydride is used, the amine group will be isolated preferentially. However, if two equivalents of acetic anhydride are used, and the reaction pushed, the diacylated product can be obtained.

The sentence is telling you that at two places on this carbon chain, the carbon #7 and carbon #12, there will by a hydroxy group attached, which is an oxygen and hydrogen together (OH). Hopefully, there is a picture that shows the shape of the chain, but I am willing to say that it is not a straight line. Next, there is an oxidation (you remember oxidation/reduction from general chem?) of the C24 alcohol. The changes made by adding these hydroxy groups, which would change the form of the protein (form = function), you will get a range of acids that are found in bile. The C24 is a carbon chain.

The aldehyde group of glucose is reduced to alcohol group to form sorbitol. The answer should be D as sorbitol is a sugar alcohol.
