Thank you for replaying.
Is it something like the following:
Group Sentence Type of article
A As you probably know… The tulip is very popular in the Netherlands. definite Singular
B As you probably know… tulips are very popular in the Netherlands. bare plural
C As you probably know… tulip is very popular in the Netherlands bare singular
D As you probably know… A tulip is very popular in the Netherlands indefinite singular
E As you probably know… The tulips are very popular in the Netherlands. definite plural
A As we all know…vets deal with sick animals. bare plural
B As we all know… The vet deals with sick animals definite Singular
C As we all know… A vet deals with sick animals. indefinite singular
D As we all know… The vets deal with sick animals. definite plural
E As we all know… Vet deals with sick animals. bare singular
I did that by using excel spreadsheet. I also have a context for each of these test sentences, and different comprehention and multiple choice questions. How can that work?
