Ochem Destroyer Question Clarification

For question 60 in the 2015 destroyer ochem section it presents 1,2 dimethyl cyclopentane and asks how many constitutional and stereo isomers exist for it. The answer is 7 because it only considers cyclicpentane isomers. Wouldn't other 7 carbon alkenes or cyclo butanes also be considered constitutional isomers? Constitutional isomers are just different ways to bond the same carbons together. There would be a ton of isomers then, too many for a multiple choice question?

 

Thanks!!
