A valid question is one that:
a) has relevance and some degree of connectivity to the topic
b) is logicall consistent (ie should have only one unambiguouis interpretation).
c) can be expected to have an answer that is realistic (ie. is known or can be known, eg with further research)
d) may have multiple answers but these should be testable (ie. evidence based). Multiple answers will probably result from imprecision in defining the question. Eg. different people may have different answers to the swame question if they have different experiences and different points of view.

You could try substituting the solution into the original question and check whether it is valid.
Sorry but your question doesn't make sense... You have to know what the hypothesis is to test if your question is valid.
