Example 3 and 4

I agree with Cécile - all look ok, if I am looking at the right examples: 

 Example 3 

«la femme française mais les femmes françaises - 

the French woman but the French women»: a word for word translation
Example 4

«un homme fort et des hommes forts» - a strong man and strong men: not word for word 

but this can arise because in English 'some' does not need to be specified in many general context/sentences, whereas in French 'des' will always be required in the phrase. It would not be wrong to include 'some' in the English translation, however - either fits.
