The structure of education in the United States), and so only the last achievement, not all, needs to be considered.
Please help with a problem with a noncount noun that can be a countable noun:
I know that certain uncountable nouns can be counted if they refer to concrete and specific instances, otherwise abstract or general.
1.a. We studied 700 mothers in town A based on their level of education.
1.b. Why not "We studied 700 mothers in town A based on their levels of education?
Thank you for your anticipated help.
Thank you for your prompt response. Please did you mean that "level" in my sentence 1.a. refers to "structure"? I am still confused as to when to use "levels" and "level" based on the general/abstract and concrete/specific matrix of noncount
But "level" is used here as a non-count noun.
Thank you Raymott for your clearer response.
Just for clarity's sake, does it mean that "level" is used in a general or abstract sense without reference to specific or concrete levels?
Yes, in that sentence it does.
Later in the article, they will have to use it in a concrete way.
"We found that their level [abstract] of education could be divided into 4 levels [concrete].
That's not a good sentence, but it illustrates the two meanings.
Thank you Raymott for your excellent help.
