Full text of example questions:
First example:
Text 1
Astronomer Mark Holland and colleagues examined four white dwarfs-small, dense remnants of past stars-in order to determine the composition of exoplanets that used to orbit those stars. Studying wavelengths of light in the white dwarf atmospheres, the team reported that traces of elements such as lithium and sodium support the presence of exoplanets with continental crusts similar to Earth’s.
Text 2
Past studies of white dwarf atmospheres have concluded that certain exoplanets had continental
crusts. Geologist Keith Putirka and astronomer Siyi Xu argue that those studies unduly emphasize
atmospheric traces of lithium and other individual elements as signifiers of the types of rock found on Earth. The studies don’t adequately account for different minerals made up of various ratios of those elements, and the possibility of rock types not found on Earth that contain those minerals.
Based on the texts, how would Putirka and Xu (Text 2) most likely characterize the conclusion presented in Text 1?
Second example:
Text 1
Ecologists have long wondered how thousands of microscopic phytoplankton species can live together near ocean surfaces competing for the same resources. According to conventional wisdom, one species should emerge after outcompeting the rest. So why do so many species remain? Ecologists’ many efforts to explain this phenomenon still haven’t uncovered a satisfactory explanation.
Text 2
Ecologist Michael Behrenfeld and colleagues have connected phytoplankton’s diversity to their
microscopic size. Because these organisms are so tiny, they are spaced relatively far apart from each other in ocean water and, moreover, experience that water as a relatively dense substance. This in turn makes it hard for them to move around and interact with one another. Therefore, says Behrenfeld’s team, direct competition among phytoplankton probably happens much less than previously thought.
Based on the texts, how would Behrenfeld and colleagues (Text 2) most likely respond to the “conventional wisdom” discussed in Text 1?
Great explanation! Thanks
I learned tone from you sir thank you for your all great efforts
Gosh,i love your videos. Thank you sir 🙏🙏.
About to take the exam. Thank you for all the help.
You're welcome. How dit it go?
Thank you so much for the video! 💖💖
You are welcome. Glad you found it helpful. Thank you for watching.
Please do November predictions for the digital sat
I would if I could, but unfortunately, I don't have any insight into what they might ask on any particular tests, especially since they aren't releasing any QAS's for previous tests.
sir could you reccomend any channel for dsat maths practice like you .please because im preparing by myself
The one I hear good things about is Scalar Learning (www.youtube.com/@ScalarLearning), although if you have any specific questions I can see what I can do in terms of putting together a quick video or two.
im taking my first SAT in may,and currently,i suck.
Don't get too discouraged. Even if the May test is difficult for you, there will still be additional opportunities in June, August, and early October.
i have 24 days left
For your college application deadlines or your next SAT date?
HI, which book do u use sir?
I don't really use a book. I use the College Board's practice tests for the questions in these videos: satsuite.collegeboard.org/digital/digital-practice-preparation/practice-tests
where's part 2?
I haven't recorded an official part 2 yet. I do have some more stuff on paired passages here:
czcams.com/video/styugPJfpFc/video.html
But if you have any specific questions or passages you'd like me to go over, let me know and I'lll see what I can do.
@@345tutoring Thank you sir !
