Regarding the use of pronouns and articles in English morphosyntax, mark T for True or F for False:
(__)The relative pronoun "whom" is used in formal registers to refer to the object of a verb or preposition, while "who" is typically used for the subject.
(__)Reflexive pronouns, such as "himself" or "ourselves", can be used with an emphatic function to stress that the subject performed the action without help.
(__)The definite article "the" must be used before names of individual lakes and mountains in academic writing to ensure the correct determination of the noun.
(__)Possessive adjectives like "their" and "her" function as substitutes for the noun, eliminating the need to express the possessed object in the sentence.
Now, choose the CORRECT alternative with the sequence from top to bottom:

The use of articles in English involves distinctions between "the" (definite) and "a/an" (indefinite), as well as sound-based rules for the use of "a" and "an".

Os artigos em Língua Inglesa (Definido: *the*; Indefinidos: *a*/*an*) são determinantes que especificam ou generalizam um substantivo. O uso correto é notoriamente difícil para falantes de português, pois as regras diferem, especialmente quanto ao uso do artigo definido (*the*) com substantivos abstratos, genéricos ou nomes próprios, e a escolha entre *a* e *an* dependendo do som inicial da palavra seguinte.

Acerca do uso dos artigos em inglês, marque V, para as afirmativas verdadeiras, e F, para as falsas:

(__)O artigo indefinido "an" é usado antes de palavras que começam com som de vogal, independentemente da letra (e.g., *an hour*, *an umbrella*), enquanto "a" é usado antes de palavras com som de consoante (e.g., *a university*, *a car*).
(__)O artigo definido "the" é usado para especificar um substantivo que já é conhecido pelo leitor/ouvinte ou que é único em seu contexto (e.g., *The sun is hot*).
(__)Diferente do português, o artigo definido "the" geralmente não é usado antes de substantivos abstratos usados em sentido geral (e.g., *Love is important*, e não *The love is important*) ou nomes próprios de pessoas (e.g., *Mary lives here*, e não *The Mary lives here*).
(__)O artigo "a" é sempre usado antes de substantivos plurais para indicar generalização (e.g., *a books are expensive*).
