This question kicked my ass

Alright I feel like the lesson questions are insanely easy, I always understand and then in the 'You Try' I get BOMBARDED with these hard questions. Is anyone else having this issue?

I feel like every time I find a pattern for the right answer it changes. I don't undersand how you are supposed to choose between the different hypotheses from questions question because all the questions feel like they're written the same way.

#feedback for Q7, how can we assume that it takes longer for experienced workers. If we are negating the fact that they are the same, then wouldn't the negation be able to work either way? aka: it could take longer for experienced OR inexperienced workers, but there is not enough information to conclude which direction it goes? #help

Can someone break Q8 down into Lawgic for me please? Which is sufficient and which is necessary?

#help This lesson has baffled me. So there is not sufficient/necessary conditions? You choose? How would this be applicable on the LSAT if there is inherently a right/wrong answer to each question? We won't be able to interpret anything in 2 ways on the LSAT or else risking getting the question wrong.

Wouldn't the correct answer have to address the decrease in traffic congestion if that is the exception/last rule that the statement must follow. I eliminated answer choices that didn't mention traffic congestion because of this.

I am also confused why in the chain traffic congestion does not come before increased profits since the sentence reads that a decrease in traffic congestion is NECESSARY in order for a business to increase their profits.
