Question
While researching a topic, a student has taken the following notes:
- As engineered structures, many bird nests are uniquely flexible yet cohesive.
- A research team led by Yashraj Bhosale wanted to better understand the mechanics behind these structural properties.
- Bhosale’s team used laboratory models that simulated the arrangement of flexible sticks into nest-like structures.
- The researchers analyzed the points where sticks touched one another.
When pressure was applied to the model nests, the number of contact points between the sticks increased, making the structures stiffer.
The student wants to present the primary aim of the research study. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A. Bhosale’s team wanted to better understand the mechanics behind bird nests’ uniquely flexible yet cohesive structural properties.
B. The researchers used laboratory models that simulated the arrangement of flexible sticks and analyzed the points where sticks touched one another.
C. After analyzing the points where sticks touched, the researchers found that the structures became stiffer when pressure was applied.
D. As analyzed by Bhosale’s team, bird nests are uniquely flexible yet cohesive engineered structures.
▶️Answer/Explanation
Ans. A
Correct Answer: A
Rationale
Choice A is the best answer. It describes the reason Bhosale’s team wanted to study the structures of bird nests—that is to say, the study’s primary aim.
Choice B is incorrect. This choice doesn’t present the primary aim of the research study. It describes how the study worked, but not why it was done. Choice C is incorrect. This choice doesn’t present the primary aim of the research study. It describes a result of the experiment, but not why it was carried out. Choice D is incorrect. This choice doesn’t present the primary aim of the research study
Question
While researching a topic, a student has taken the following notes:
- The Million Song Dataset (MSD) includes main audio features and descriptive tags for popular songs.
- Audio features include acoustic traits such as loudness and pitch intervals.
- Many algorithms use these audio features to predict a new song’s popularity.
- These algorithms may fail to accurately identify main audio features of a song with varying acoustic traits.
- Algorithms based on descriptive tags that describe fixed traits such as genre are more reliable predictors of song popularity.
The student wants to explain a disadvantage of relying on audio features to predict a song’s popularity. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A. Many popularity-predicting algorithms are based on a song’s audio features, such as loudness and pitch intervals.
B. Algorithms based on audio features may misidentify the main features of a song with varying acoustic traits, making such algorithms less reliable predictors of popularity than those based on fixed traits.
C. Audio features describe acoustic traits such as pitch intervals, which may vary within a song, whereas descriptive tags describe fixed traits such as genre, which are reliable predictors of popularity.
D. The MSD’s descriptive tags are reliable predictors of a song’s popularity, as the traits they describe are fixed.
▶️Answer/Explanation
Ans. B
Correct Answer: B
Rationale
Choice B is the best answer. This choice uses relevant information from the notes to explain a disadvantage of relying on audio features to predict a song’s popularity—namely, that it may misidentify features of certain songs. It also contrasts audio features with descriptive tags, which are more reliable predictors.
Choice A is incorrect. This choice only states a fact about the algorithms without evaluating their reliability or accuracy. Choice C is incorrect. This choice only describes the difference between audio features and descriptive tags without indicating why this difference matters for predicting popularity. Choice D is incorrect. This choice only mentions descriptive tags, which are not the focus of the student’s rhetorical goal.
