Hi, I have major verb-tense problems and I would appreciate it very much if you can help me with it. Thanks.<br/><br/>This sentence doesn't sound right.<br/><br/>1. People who <i>oppose</i> the pronoun ‘they’, can argue that ‘they’ <i>has</i> a root word ‘he’, thus it is <i>biased</i>.<br/><br/>...and can you explain why there needs to be an -ed at the end of bia. Thanks again.<br/><br/>2. These biased and exclusive terminologies...
