This question already has an answer here:
I checked the grammar of my research article using a leading software. This is my sentence:
- A total of 12.3 million sequences was used for the establishment of database.
The error is: 'Potential issues with passive voice usage'
Anything wrong here?
(NOTE: Er, the OP's question is about passive voice, but the "duplicate" linked thread is about subject-verb number agreement. Perhaps there's a related issue here, on subject-verb number agreement (which is debatable), but the OP's main question on passive voice ought to be addressed. Anyway, a short answer post here would probably be more appropriate than a related link. -- F.E.)
