<span>Margot and an unnamed narrator are musing about a fantastical scenario in which they catch neighborhood children with a fishing pole, bathe them, mend their clothes and then presumably return them to their previous occupation of walking by Margot's house. Though altruistic in nature, Margot and the narrator might find the children less than eager to participate in this spontaneous bath.</span>
It is silly, person above is correct
Answer: Our paper's science writer, whose column I read every week, recently reported on exoplanets.
Explanation: There are three ideas here.
1. Our paper's science writer
2. They recently reported on exoplanets
3. How I read their column every week.
Two of the ideas are included in the sentence (1 and 2), and the last simply needs to be modified.
"Whose" is a determiner and associates things with other things. In the last idea, we associate their column to them: whose column... Then, we add how I read it every week and say, "...whose column I read every week."
