Explanation:

- Let's break the columns:

- Column 1:

- A. "The scientist"

- B. "He had"

- C. "She went"

- Column 2:

- D. "conducted several experiments"

- E. "often spoken about"

- F. "to the market"

- Column 3:

- P. "for groceries"

- Q. "before publishing"

- R. "his findings"

- Matching these logically:

- BDQ: "He had conducted several experiments before publishing." (Correct)

- BFR: "He had to the market his findings." (Incorrect)

- CDQ: "She went to the market before publishing." (Incorrect)

- CFP: "She went to the market for groceries." (Correct)

- AFR: "The scientist often spoken about." (Incorrect)
