I have two questions about the use of gerund. The first thing is that gerund can have articles when they are used as noun. Also, I wonder if they can have articles before the noun when they are used to make a compund noun.
1) Ms. Fell's experiencing makes her an ideal candidate.
2) Carefully examining the problem is important.
3) All commercial catering businesses refrigerate perishable food to prevent it from spoiling.
Finally, I have read some explanations from a TOEIC book that says " in order to distinguish the form of -ing and general noun, you shoud think whether they are countable and uncountable as well as its meaning. However, the book has no example sentences, so could please give examples along with some explanations. The book only has example words, such as "advertisement vs advertising", "fund vs funding", process vs processing", "market vs marketing", "mail vs mailing"
Thank you in advance
