Are these sentences correct? Is there any difference in meaning between #1 and #3?<br/><br/>1. What <b>is</b> the make and what <b>is</b> the year of your car?<br/><br/>2. What <b>is</b> the make and year of your car? - Is 'what is the year' omitted in this sentence?<br/><br/>3. What <b>are</b> the make and year of your car? - is this sentence correct? Is the subject 'make' and 'year'?<br/><br/>Thanks
