When to use that and when to use which
Confused about the correct usage of the pronouns that and which? Learn from this English tutorial thread when each of these should be used.
Not just while contributing my own articles or submitting a forum thread, even while editing, I get a little confused about the correct usage of the word 'that' and the correct usage of the word 'which'. Take this sentence, for example:
People eat more junk foods that supply high amount of calories.
Is the word 'that' correctly used here? Or should it be:
People eat more junk foods which supply high amount of calories.
I would also like to know if English in the sentence itself is entirely correct. Should there be 'a' before 'high'? Should the word 'foods' be singular?
Further, with reference to the vocabulary, is this better:
People eat more junk foods which include a high amount of calories. ('include' instead of the word supply)
Lots of questions! Can anyone at ISC resolve my confusion?
