Original sentence: "Science is largely based on testing disprovable hypotheses through collection of quantitative data".
I was told by a professor that "collection" would need to be preceded by "the". I originally wrote the sentence as shown above, since I had seen the exact phrasing multiple times in many different forms of writing, and also because I thought "collection of quantitative data" was used as an uncountable noun here, meaning it would not need an article.
In any case, I would like to know if my original sentence is grammatically correct or incorrect with reference to specific grammatical rules, if possible.
Thank you :)
