Another flaming post

Now I shall disclose another fact about myself. I suffer from a inferiority complex. So I came back again to flame the same school that made the mistake on the previous chem paper.

OK, notice the propanoic acid part. Then count the number of carbons. Damn fail right? And there's another problem to this question. It assumes that by stating adding con. sulfuric acid, we should know that it's a dehydrating reaction. But the problem here is, the compound has both a carboxylic acid group and an alcohol group. Hence, the first thing that I thought about was that it'll form an ester by itself (or a more complicated carboxylic acid since it has the higher priority in naming). There's also another possibility that this thing goes through condensation polymerisation and forms a macromolecule. :O Hence, I never understood why this is actually regarded as a more challenging question that can come out for higher paper. My chem teacher went, "Why you question (name of school) so much?", when I first showed some doubts about how weird some questions were. However, she gave in by saying "Aiya (name of school) la (name of school) la", when I showed her this question. She should take some stuff from the JC and let us try.
