an SAT question a day keeps the brainrot at bay

prepping for the SAT, or just love to answer Tumblr polls? welcome to the only blog posting SAT multiple choice questions every day.

[sat-a-day]

Welcome to SAT-a-day!

I'm MJ (@catstrophysics)! This blog is a result of my side gig as a standardized test/physics tutor, and I thought it would be fun to post SAT multiple choice questions as polls on here to sate the Tumblr user desire to click buttons.

Each question will be open for 3 days, after which I'll comment with the correct answer and a brief explanation of how to do it/any tips and tricks.

If you're a high school student looking for an actual SAT/ACT/physics tutor, please feel free to DM me, and I'd love to work with you!

Tags are below the read more. Not in any way afflilated with CollegeBoard or any other standardized test organization. Thanks for reading!

#math - Questions from the math sections. The adaptive digital SAT allows the use of calculators on all questions, but try to do it without one for a challenge!

#ebrw - Questions from the evidence-based reading and writing sections.

#math answered - Math questions with completed polls that have had an answer explanation posted.

#ebrw answered - English questions with completed polls that have had an answer explanation posted.

Wrong blog for that last post maybe?

I owe you my life (and my dignity), I am so bad at managing having multiple blogs...

The mimosa tree evolved in East Asia, where the beetle Bruchidius terrenus preys on its seeds. In 1785, mimosa trees were introduced to North America, far from any B. terrenus. But evolutionary links between predators and their prey can persist across centuries and continents. Around 2001, B. terrenus was introduced in southeastern North America near where botanist Shu-Mei Chang and colleagues had been monitoring mimosa trees. Within a year, 93 percent of the trees had been attacked by the beetles.

Which choice best describes the function of the highlighted sentence in the overall structure of the text?

It states Chang and colleagues' hypothesis about mimosa trees and the beetles.

It presents a generalization exemplified by mimosa trees and the beetles.

It provides context that clarifies why the species spread to new locations.

It offers an alternative explanation for the findings of Chang and colleagues.

“i am not from a country that takes the sat so it is very interesting to see what other people are tested on and if i would be able to do it :) also probably very helpful for people who are actually studying to do the sat!!”

What an honor to be up against one of my personal favorite gimmick blogs! Nevertheless, vote sat-a-day! Break up your dash with a little extra thinking! Try out this question:

In 2014, Amelia Quon and her team at NASA set out to build a helicopter capable of flying on Mars. Because Mars’s atmosphere is only one percent as dense as Earth’s, the air of Mars would not provide enough resistance to the rotating blades of a standard helicopter for the aircraft to stay aloft. For five years, Quon’s team tested designs in a lab that mimicked Mars’s atmospheric conditions. The craft the team ultimately designed can fly on Mars because its blades are longer and rotate faster than those of a helicopter of the same size built for Earth.

According to the text, why would a helicopter built for Earth be unable to fly on Mars?

Because Mars and Earth have different atmospheric conditions

Because the helicopter blades built for Earth are too large to work on Mars

Because the gravity of Mars is much weaker than the gravity of Earth

Because helicopters built for Earth are too small to handle Martian conditions

As British scientist Peter Whibberley has observed, "the Earth is not a very good timekeeper." Earth's slightly irregular rotation rate means that measurements of time must be periodically adjusted. Specifically, an extra 'leap second' (the 86,401st second of the day) is ______ time based on the planet's rotation lags a full nine-tenths of a second behind time kept by precise atomic clocks.

In 2007, computer scientist Luis von Ahn was working on converting printed books into a digital format. He found that some words were distorted enough that digital scanners couldn’t recognize them, but most humans could easily read them. Based on that finding, von Ahn invented a simple security test to keep automated “bots” out of websites. The first version of the reCAPTCHA test asked users to type one known word and one of the many words scanners couldn’t recognize. Correct answers proved the users were humans and added data to the book-digitizing project.

Which choice best states the main purpose of the text?

To discuss von Ahn’s invention of reCAPTCHA

To explain how digital scanners work

To call attention to the book digitizing-project

To indicate how popular reCAPTCHA is
