because they wanted to make a better living. Others received letters from friends or family members who had moved west. These letters often told about a good life on the frontier. The biggest factor that pulled pioneers west was the opportunity to buy land.
Answer:
This is a compound sentence made up of two independent clauses, so no comma is needed.
Explanation:
Independent clause#1:
Beatrice was unable to concentrate on her project.
Independent clause#2:
Her brother's stereo was turned up to full volume.
Both clauses are explainable on their own and do not depend on another clause.
"To try to write certain sentences is difficult"
The correct statements are 1, 2 and 3.
1) The sentence is correctly written. The pattern "to try to do something" is correct and can be used.
2) The sentence contains more than one infinitive. It contains two infinitive verbs. TO TRY and TO WRITE.
3) One infinitive is inside another infinitive phrase. "To try to write certain sentences" is an infinitive phrase, it functions as a noun because it is the subject of the sentences. So, the second TO INFINITIVE is inside the main infinitive phrase. (That is the reason why number 4 is not correct)
