Can someone share how they got the right answer without using conditional logic? Or if they found it more helpful not to draw out the logic?

Hi I’m having trouble joining. Can you post a new link please?

I'm interested

Thanks for sharing your journey! This was very helpful. Best of luck to you!

Also I'm realizing that the stim doesn't say that the insects are attracted to one specific pattern. Just that each thing has their own distinctive (characteristic) pattern. And each distinctive pattern from the reflection is how they sense the UV light.

So all we have to bolster that it is infact the UV light (nothing more nothing less) that attracts the insects.

I've read through the comments a bit and saw that some people felt that D is attacking the conclusion entirely.

After re-reading more closely, it actually isn't.

part of the premise is that the co2 levels were "surprisingly" low, meaning that those low levels were unusual.

Also given the premise, that algae absorbs co2 ( assumption that more algae lower co2 levels)

Another assumption that the author wants you to make is that there must've been a higher that normal amount of algae to explain why the small co2 were surprisingly.

The author makes the conclusion that since ferrous material was found in unusually high amounts in the atmosphere, that it must've caused the increase in algae leading to the super low co2 levels.

D weakens the argument bc its saying: there was no (great) increase (from the normal) in the shells left behind when there are lots of diatoms. So basically, there wasn't more shells than usual left behind.

The conclusion says that ferrous material not just increased but GREATLY increased algae pop.

D says there's actually not evidence of a great increase.

Sorry in advance if I didn't explain this correctly.

I’m interested, if you all still have space. I’m averaging in the 160s.

I’m also interested!

What's the difference between an MSS Least vs an MSS Except question?

yeah, same. rereading this passage made me question what "barely meets" is even understood to mean

I'm down

I'm Interested!
