Question 191·Medium·Rhetorical Synthesis
While researching a topic, a student has taken the following notes:
- Jocelyn Bell Burnell is an astrophysicist from Northern Ireland.
- In 1967, as a graduate student at the University of Cambridge, she discovered the first radio pulsars.
- The discovery earned the 1974 Nobel Prize in Physics, but it was awarded to her male supervisor and another astronomer.
- Bell Burnell later became the first female president of both the Royal Astronomical Society and the Institute of Physics.
The student wants to write a brief introduction to Jocelyn Bell Burnell and her landmark discovery.
Which choice most effectively uses relevant information from the notes to accomplish this goal?
For rhetorical synthesis questions, restate the goal in your own words (here: “Introduce Bell Burnell and clearly state her landmark discovery”). Then select the notes that directly serve that goal—typically identity + key action + significance—and choose the option that accurately combines those points without drifting into side details or leaving out the discovery.
Hints
Focus on the task words
Underline the words “brief introduction” and “her landmark discovery.” Which choice gives you both a clear sense of who she is and what major thing she did?
Decide which notes matter most
Look at the bullet points and ask: Which ones explain her identity and the big discovery itself, and which ones are extra background or later achievements?
Eliminate too-narrow choices
Cross out any option that talks mainly about the Nobel Prize issue or her leadership roles but does not clearly state what she discovered and why it was important.
Check for direct connection between person and discovery
Make sure the sentence clearly links Jocelyn Bell Burnell to the discovery itself (not just to astronomers in general or to people around her).
Step-by-step Explanation
Understand the writing goal
The student wants a brief introduction to Jocelyn Bell Burnell and her landmark discovery. So the best option should (1) identify who she is and (2) clearly state what she discovered, ideally with a detail that shows why it mattered.
Identify the most relevant notes
The most relevant notes for this specific goal are:
- She is an astrophysicist from Northern Ireland.
- In 1967, as a graduate student at the University of Cambridge, she discovered the first radio pulsars.
- The discovery was important enough to earn a Nobel Prize in Physics (even though it was awarded to her male supervisor and another astronomer).
Her later leadership roles are impressive, but they are not the central focus if the goal is her landmark discovery.
Check each choice against the goal
- Choice A adds background about the Nobel Prize but still never names the landmark discovery (radio pulsars), so it’s not effective for introducing her discovery.
- Choice B mentions pulsars and Cambridge but credits “radio astronomers” generally rather than clearly stating that she made the discovery, and it shifts to her later leadership roles.
- Choice C introduces who she is and mentions later achievements, but it still does not state what the landmark discovery was.
- Choice D identifies her, states the discovery, gives the time/place context, and includes the Nobel Prize detail to show significance.
Select the most effective introduction
Therefore, the best choice is:
Northern Irish astrophysicist Jocelyn Bell Burnell discovered the first radio pulsars in 1967 as a graduate student at Cambridge; the breakthrough later earned a Nobel Prize in Physics, though it went to her male supervisor and another astronomer.
