A question is an utterance which typically functions as a request for information, which is expected to be provided in the form of an answer. Questions can thus be understood as a kind of illocutionary act in the field of pragmatics or as special kinds of propositions in frameworks of formal semantics such as alternative semantics or inquisitive semantics. Questions are often conflated with interrogatives, which are the grammatical forms typically used to achieve them. Rhetorical questions, for example, are interrogative in form but may not be considered true questions as they are not expected to be answered.

    Hi everyone, I have bare pipes under the kitchen sink and also in a cupboard next to my bathroom. Is it a good idea to put foam wrap on them and if so should the wrap be on both hot and cold water pipes or just the hot water pipes? Thank you any advice would be appreciated.

It wasn't huge, but I decided I'd better do the reasonable rational thing and rip the whole thing out! I thought, I can get an acrylic one from Bunnings and...
