Hi,<br/><br/><br/><br/>Are the following sentences natural to a native ear?<br/><br/><br/><br/>1. She will be here at 6.00 pm, 5 minutes up or down.<br/><br/><br/><br/>2. The numbers I sent you yesterday <u>were</u>/<u>are</u> correct. ( I am not sure whether ‘were’ is appropriate because the fact that they are true still exists)<br/><br/><br/><br/>3. If he was sick, why didn’t the school send him to <u>the/a</u> doctor?<br/><br/><br/><br/>Thanks,<br/><br/><br/><br/>MG.
