1. Chris can do the job, isn't he?

2. Chris can do the job, isn't she?

(Which tag question is right? Are both OK? Is Chris used as a male name or female name?)

Chris is both a girl's and a boy's name. A better way of asking that question would be, "Chris can do the job, can't she?"

1. The correct tag question would be "can't he?". The name "Chris" is commonly used for both males and females. In this case, it is assumed that Chris is a male, so the correct pronoun to use in the tag question is "he."

2. The tag question "isn't she?" would be grammatically incorrect in this context because "she" implies that Chris is a female. However, if you wanted to refer to Chris as a female, the correct sentence would be "Chris can do the job, can't she?" with the appropriate pronoun.

In general, it's important to use the correct pronouns based on the gender of the person you're referring to. If you're uncertain about someone's gender or prefer to use gender-neutral language, you can simply use their name instead of pronouns in the tag question, like "Chris can do the job, can't Chris?"
