- For Teachers
Studies related to the physiology and biochemistry of seedling growth as affected by air pollutants has or have drawn interest in current years.
I should have figured that out....studies being plural, therefore, it takes a plural verb - have. Thanks!
You are welcome. Don`t worry ! I sometimes make mistakes too and I shouldn`t , especially because I am a teacher of English and I am not supposed to make mistakes. I have been studying English since I was 10 years old [ I`m 51 now] and I still make mistakes.
