Question 1

Photographs of planet Earth taken from satellites show an exquisite spherical body with an apparently smooth, clearly defined surface. However, we who dwell on the Earth’s surface have a different perspective: we know that the surface includes both miles-high peaks and miles-deep valleys.

Which transition word could be substituted for the word “however” without changing the meaning of the sentence?

Accepted Answer

Yet

Answer

Explanation:
The word "yet" can be used as a synonym for "however" to indicate a contrast between two statements. In this context, "yet" effectively conveys the contrast between the perspective from space and the perspective from the Earth's surface, similar to how "however" does.

Question 2

The valleys, on the other hand, present daunting challenges—submerged under oceans, many of these valleys remain elusive to all but a tiny number of daring, highly motivated explorers.

What is the meaning of the word “daunting” as it is used in this sentence?

Accepted Answer

Formidable

Answer

Explanation:
The word "daunting" means intimidating or challenging, suggesting something that is difficult to overcome. "Formidable" is a synonym that conveys a similar meaning, indicating something that inspires fear or respect due to its size, power, or difficulty. In this context, "daunting challenges" refers to the difficult and intimidating nature of exploring the submerged valleys.

Question 3

Which best describes the main idea of this paragraph:

The first human mission to the bottom of the trench was in 1960, when engineer Jacques Piccard and submariner Don Walsh descended in a deep sea submersible called the Trieste. It was 52 years before the second descent, by Titanic filmmaker James Cameron. In 2019 and 2020, explorer Victor Vescovo and various companions braved the gloomy depths five times. Having previously climbed to the summit of Mt. Everest, Vescovo and his companion Vanessa O’Brien have achieved the remarkable distinction of reaching both the highest and the lowest points on the planet. Another companion has accomplished a different singular feat. Kathy Sullivan is a former astronaut who walked in space in 1984. As an explorer of both oceanic depths and extraterrestrial heights, she has contemplated the earthly sphere from afar and probed its deepest inner recess.

Accepted Answer

The paragraph highlights the notable achievements and bravery of the individuals who have descended into the Mariana Trench, emphasizing their remarkable distinctions and accomplishments. This aligns with the main idea that these explorers are a daring and accomplished group.

Question 4

Looking closer, Vescovo concluded that it was that ubiquitous artifact of twenty-first-century life— a plastic bag!

What is the meaning of “ubiquitous” as it is used in this sentence?

Accepted Answer

Universal

Answer

Explanation:
"Ubiquitous" means present, appearing, or found everywhere. In this context, it describes the plastic bag as a common and widespread artifact of twenty-first-century life.

Question 5

I like biology, but I'm taking cell biology 301 next semester, which looks difficult.

Which option uses correct capitalization?

Accepted Answer

biology, but I'm taking Cell Biology 301

Answer

Explanation:
The word "biology" should be lowercase because it is not at the beginning of the sentence and is not a proper noun in this context. "Cell Biology 301" is the specific name of the course, so it should be capitalized.
