WAEC - English Language (2000 - No. 46)
The hunter, with his dogs,......... going into the forest.
was seen
are being seen
have been seen
were seen
Explication
The sentence would read:
"The hunter, with his dogs, was seen going into the forest."
Here, "was seen" is correct because the subject of the sentence is "The hunter," which is singular. The phrase "with his dogs" does not change the singular nature of the subject.
