If "Three greyhounds are racing on a track at night.", does this mean that "The greyhounds are racing on a track."?

OPT:
[i] yes
[ii] it is not possible to tell
[iii] no
user
[i] yes

The correct answer is [i] yes. The original sentence, "Three greyhounds are racing on a track at night," clearly states that the greyhounds are racing on a track. The fact that it is happening at night is an additional piece of information that does not change the core fact that they are racing on a track.

[ii] it is not possible to tell - This option is incorrect, as the original sentence clearly states that the greyhounds are racing on a track.

[iii] no - This option is also incorrect, for the same reason as option [ii]. The original sentence makes it clear that the greyhounds are racing on a track.
