Cool um where is the question?
The number of rooms can be counted, in this case one since they used the word ‘the’. I guess technically you could count that air molecules haha.
The is a determiner, first is a number, professional is an adjective, baseball is an adjective, league is a noun, was is a verb, later is an adverb, started is a verb, in is a preposition, 1871 is a number.
The answer is B.) The American government forced American Indians to leave the land.
Hope this helps:)
