Section 1, Module 1 : Reading & Writing

Researchers Dr. Amy Hertz and Dr. Brian Mur conducted a study on the acoustic properties of various wood types, measuring changes in sound velocity and density over ten years. Sound velocity in wood is crucial for musical instrument quality, and it can change due to environmental factors like humidity and temperature. Dr. Hertz and Dr. Mur concluded that while all wood types showed changes in sound velocity over the time analyzed, certain woods displayed more pronounced increases as a result of density changes.

Which choice best describes data from the bar graph that support the researchers conclusion?
A
Mahogany showed the most significant change in sound velocity, indicating its greater sensitivity to environmental changes.
B
All of the woods observed a change in velocity, but only maple, oak, ash, and spruce observed density changes.
C
None of the wood types observed a velocity change of less than 100 m/s and maple observed the greatest change in sound velocity when considering woods that underwent density changes.
D
Maple displayed the least significant velocity change and oak displayed the greatest velocity change when examining woods that underwent density changes.

Hello, I am a senior who is currently preparing for the SAT. Bluebook only provides about three practicesAnd I found out about Test Qube while I was having a hard time preparing for the test as the SAT changed to digital To share what I felt while writing Test Qube I felt that the biggest advantage of Test Qube was that it was the same as the actual test in many areas From UI to test time limit, and in this part, I thought that even those who have never taken the SAT could practice enough through Test Qube Personally, I tend to get very nervous when taking exams, but Using Test Qube for practice greatly reduced my exam anxiety It's too good to keep it to myself. It would be a shame to keep it to myself. Thank you Test Qube!!!
