I think that the rule requiring agreeing-words to be feminine singular applies, not when the SUBJECT of the verbal sentence is plural, but only when the SUBJECT-NOUN (or 1st one, if there is more than one) is plural. So the rule applies to sentences in which the subject is in the form "The As" or "The As + B + C," but not in the form "A + the Bs." However, how in a sentence with its subject in the form "A + the Bs" would Arabic usage deal with the underlined words of a sentence such as "The palace and museums of London please us because they are beautiful and remind us of the past ?"
