In sentence one from paragraph C, there is a spelling mistake in the verb *<em>studyed</em>. In that respect, when adding an inflectional morpheme like the past simple regular suffix <em>-ed</em>, if the verb ends with a consonant followed by <em>-y,</em> then the <em>-y</em> plus <em>-ed</em> becomes <em>-ied</em>. As a result, the correct revision of *<em>studyed </em>is studied.
