Is the following sentence correct?
His selection was based solely on his grades and extra-curricular activities
(The context here is that I want to emphasize that this person was selected in a fair manner i.e. on the basis of grades and extra curricular activities alone.)
I'm confused because I do not know if I can write multiple reasons for selection if I've used solely.
I've looked at the definition of solely in Merriam Webster :
1. without another
2.to the exclusion of all else
So by definition 2, I think my sentence would be correct, but I'm not sure.
