Hello,<br/><br/>Is this appropriate to treat the plural as a singular noun collectively?<br/><br/>"WDAP application<u><b>s</b></u> such as t-learning and s-learning <u><b>is</b></u> <b><u>an alternative model</u></b> to the existing model."<br/><br/>If the above is wrong, any better suggestions? <br/><br/>eg. "WDAP application<i><u> </u></i> including as t-learning and s-learning <u><b>is</b></u> <b><u>an alternative model</u></b> to the existing model."<br/><br/>Thanks a lot.
