Hi,<br/><br/><i>A: Why? </i><br/><br/><i>B: To get information about the science behind the whitening effect <u>that is used</u>.</i><br/><br/>Q1) What is the antecedent of the relative clause?<br/><br/>I think it's 'science'. Am I correct about this?<br/><br/>Q2) Why is it that the relative clause doesn't follow immediately its antecedent? Any reason why it's positioned at the end of the sentence?<br/><br/>Thanks in advance for your help.
