I had the same question, and this is what I did.
Sore muscles during vigorous exercise
Answer: 1,3&4
Explanation:
The lac operon is induced by lactose in the absence of glucose, this is because when lactose is present in the medium, lactose binds to the repressor protein, one molecule on each subunit, causing a conformational change in the repressor.
The Repressor-lactose complex is in active, so the repressor does not bind to the operator site.
RNAP binds to the operator, identifies the promoter sequence and transcribe the structural genes.
RNAP can attach to the promoter site only when CAP doesn't bind the operator. In the absence of glucose in bacteria cAMP is available which combines with CAP, preventing CAP from binding the promoter site.
He could race multiple cars with different weight added on them and do multiple races (just to be sure) and see if his theory was correct, if not he should right down what he has learned from his experience! :D
