Hi teachers,<br/><br/>Why "gas reserves" is used in stead of "gas reserve" when "make <b>it</b> into" seems incongruous with it in this sentenc?. Thanks.<br/><br/>The then President Vladimir Putin vowed to use the country's vast gas reserves to make it into an "energy superpower." <br/><br/><br/><br/>Regards,<br/><br/>Tinanam
