GMAT Expression of Ideas : (Expression) Questions
During academic research, a student has compiled these notes:
- British chemist Dr. Rosalind Franklin conducted important scientific work.
- Among her most significant X-ray crystallography photographs was Photo 51.
- This photograph was taken by Franklin in 1952.
- The photograph offered vital proof supporting DNA's double helix configuration.
- Watson and Crick incorporated some of Franklin's DNA research findings into their subsequent Nobel Prize-winning discoveries.
The student aims to present Dr. Rosalind Franklin and her Photo 51 work to an unfamiliar audience.
Which option best utilizes pertinent details from the notes to achieve this objective?

Step 2: Interpret the Question Precisely
This is a fill-in-the-blank question asking us to choose the best logical connector. The answer must create the right relationship between what comes before and after the blank.
Step 3: Prethink the Answer
- For an unfamiliar audience, the right answer should include: Franklin's identity and credentials, what Photo 51 actually is, when it was created, and why Photo 51 matters scientifically.
Dr. Rosalind Franklin took Photo 51 prior to Watson and Crick's research efforts.
✗ Incorrect
- Focuses only on timing relative to Watson and Crick's work.
- Doesn't identify who Franklin is or explain what Photo 51 is.
British chemist Dr. Rosalind Franklin took Photo 51 in 1952, among her most significant X-ray crystallography photographs, which offered vital proof supporting DNA's double helix configuration.
✓ Correct
- Identifies Franklin as "British chemist"
- Explains Photo 51 as "among her most significant X-ray crystallography photographs"
- Includes the date (1952)
- Explains the scientific importance as "vital proof supporting DNA's double helix configuration"
Photo 51, a significant X-ray crystallography photograph taken in 1952, demonstrated DNA's double helix configuration through a British chemist's work.
✗ Incorrect
- Explains Photo 51 well but doesn't name Franklin specifically, saying "a British chemist's work" instead.
Watson and Crick incorporated some of Dr. Rosalind Franklin's DNA research findings into their subsequent Nobel Prize-winning discoveries.
✗ Incorrect
- Focuses on Watson and Crick rather than Franklin and Photo 51.
- Doesn't explain what Photo 51 is or its significance.
