This passage looked easy but turned out quite tricky. Got 2 wrong out of 3 because of careless mistakes.

Even I've got the answer BCB, third one is wrong, I think following might be the explaination of third answer:
"hallucinogenic drugs other than LSD do not inhibit serotonin", So there are drugs which do not inhibit Sertonin and cause hallucinogenic effect. As per claim by Jacob , Serotonin must be 0 for dreaming. Again it is stated in the start of paragraph that "dreams and hallucinations share a common neurochemical mechanism". So, answer of third question is "D" instead of "B"

Hi,
For question number 1, the answer is B. As written - LSD mimics serotonin well enough to be able to bind at most of the neurotransmitter’s receptor sites, largely inhibiting normal transmission.
although I mi ticked E - silly mistake as it can happen only above 20mg....
