Answer 2

a) Identificamos que o pronome é plural, por causa do "are"; com o advérbio "there", identificamos que a pessoa está longe. Portanto, o mais apropriado é THOSE.
Who are those women there?

b) Novamente está no plural, mas percebemos que estão perto, pois o garoto(a) está apresentando seus amigos. Portanto, é THESE.
Mr. Ferguson, these are my friends Grace and David.

c) Está no singular; se está longe
Who's that girl at the reception?

d) Plural, e como está havendo uma apresentação, com certeza está perto.
Mrs. Grant, this is my friend Laura.

e) plural; longe
Mr. Lewis, are those boys at the library good or bad students?

f) singular, longe
Is that man there a good mechanic?

g) plural, perto
Mrs. Curtis, here are Mr. Parker and Mr. Parker and Mr. Carter. These gentlemen are from England.
