I came across this issue when I was doing June 2020 Section 2 Question 25. I thought unrepresentative sample applied because the sample was on [test subjects before experiments] and the conclusion was on [test subjects after experiments]. But a few people have told me that the "unrepresentative sample" answer choice is only for statistically unrepresentative things, like only interviewing 10 people when the population is 100,000.

I eliminated B under the "wrong" conclusion (that it was about needing accurate assessments). "It's not necessary that students can wisely and insightfully assess a professor's performance before the end of the semester because what if, magically, the students all assess the performance at the end of the semester anyway?" Would this be a correct elimination under the "imagined" conclusion? #help (Added by admin)
How do we know the song was useful or helpful at all? All we know is that the children were taught a song with their phone numbers and at the end of the day they could remember it. Like J.Y said, maybe they completely forgot it after a few minutes and then the teacher taught them another method of remembering their phone numbers (like beating it into them) #help
Isn't the conclusion that the incentive was removed? I thought that was the trick and the correct answer would talk about causation

I understand that this is a MSS question and answers to MSS questions have leeway and can be weaker. But I understood E and still eliminated because there are many ways for there to be less not preserved wood vehicles.... like maybe the archaeologists just couldn't find them. Maybe they just didn't make a lot.
I would like to point out that Avengers only beat out Avatar in the domestic box office
I chose D but I was very hesitant because don't we have to assume that the institute is a new sleeping environment? The 50 participants could've been living in the institute for years because idk, it's hard to come by reliable insomniacs?
