Spanish language Q&A Forum

There's a quiz question that I got wrong because there is no indication whether the speaker sees the event as probable or not.  A note on this would help so we don't have to guess.

I did struggle to understand why "se recordaba" was in the singular in "... solo se recordaba a los difuntos el 1 de noviembre" [= "the deceased were only remembered on November 1st"].

At first, I was tempted to make it plural to agree with "difuntos". As a passive construction, I thought it could be compared with "se venden apartamentos de lujo en la playa" - (given as one of the examples in Forming the Spanish passive with se (la pasiva refleja) ... which is the lesson we get referred to).

Anyway, I was also "scratching my head" regarding the use or non-use of the "personal 'a' " in a passive sentence of this nature - [Compare "Se buscan secretarias con experiencia" in that^ same lesson] ..

I then looked in my grammar book [by Butt and Benjamin], and discovered that this is part of a construction which evolved comparatively recently in the Spanish language - in which the use of the "personal 'a' " makes a singular verb necessary even when the [passive] subject is in the plural.
