"Destined" has to do with "fate", either good or bad. "Doomed" can also have to do with fate, but only bad. I agree that both are correct.Originally Posted by jiang
One can "conceive" an idea. One can also consider an idea conceived by someone else. Because the subject is the generalized "scientists", I would choose A. It is likely that the idea was conceived by one group of scientists or another.No.2
Scientists first________the idea of the atom bomb in the 1930s.
a. conceived b. considered
'a' is certainly correct. But what's wrong with 'b' ?
Your confusion is understandable. Nutrients is obviously a countable noun, as it is in the plural. The reason for amounts here is that the level/amount of each nutrient is important. "Number(s)" of nutrients would refer to counting the nutrients, rather than measuring them.No.3
The following is error correction:
In laboratory tests, nutritionists look for the numbers of nutrients patients have in their bodies.
According to the key 'numbers' should be corrected to 'amounts'. The reason for this is that 'nutrients' is an uncountable noun. This is so confusing that I can't figure it out. My questions are: 1. Why 'amounts' instead of 'amount'? 2. If it is uncountable noun why 'nutrients' which is obviously in plural form?
calcium - 700 mg
potassium - 200 mg
sodium - 400 mg
The number of nutrients would be three. The amounts of nutrients would be the individual values.
You can correct it to "frequently" -- an adverb. :wink:No.4
How frequence do you eat a raw vegetable salad?
According to the key 'frequent' should be corrected to 'often'. My question is: Can I correct it to 'frequent'?
