Their is no answer for just ms
No, the forecast for tomorrow night is calling for partly cloudy skies, not rain.
This is correct sentence
I would have to say that the best way to revise sentence four is by changing "aren't" and "they're" to "are not" and "they are."
"Argue" works better than "fight."
Deleting the entire sentence would remove the transition into cost efficiency of the tablets.
And moving the sentence to the end would place the transition to cost efficiency in the wrong place.
