PT35.S1.Q22 - Members of Pteropsida

Hi, I’m not sure why I am so stuck on this question but can someone help me help me? I think I am a bit lost on how to write the conditionals. Thanks

It is definitely to your benefit to drill the crap out of conditionals and get super comfortable translating text into lawgic! Questions like these become much more easy

Once you translate the premises, this is what you get:
chordate ------> tracheophytes

Pteropsida ----> tracheophytes --------> chordate

Conclusion is:
Pteropsida ----> homindae

In order to "fit" the premises and the conclusion together, you need to tack on the last bit of conditional logic to the end of the premises, which would be

chordate --------> homindae
OR
homindate -------> chordate
