Lady Capulet observes that Juliet "was too young to know that there is little more useless than a boy." What themes about love and duty are revealed through
through her point of view?

To her, duty is more important than love

Explanation:

Lady Capulet relates Juliet's understanding to that of someone who still does not have requisite understanding due to her age. Her statement, that there is little more useless Than a boy means that indulging in a relationship is almost the last thing one should adore or get preoccupied with. Therefore, we can deduce that Lady Capulet gives significantly more credence to duty than love. Hence, she feels Juliet's who has given in to love is mistaken and ties Juliet's understanding to her lack of experience.

faulty parallelism is a grammar construction where there is no balance in the parts of a sentence they have a similar meaning but the grammar structure is not equivalent.

the correct version of this faulty parallelism in the sentence is:

jefferson wrote the declaration of independence, and he was the nation's third president.

the problem with the first version is that the sentence:

"jefferson was both the writer of the declaration of independence"

presents jefferson as both a subject and an agent for the verb "write" because if he was "the writer" then the declaration of independence was written by him, besides that fact, the sentence presents a dependent clause.

while the second sentence:

he was the nation's third president.

presents a basic subject+verb+object structure

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in both sentences:

jefferson wrote the declaration of independence, and he was the nation third president.

1) technical language (writen technical volcabulary)

2) ordinary langauge

3) literary language (because it's text with a rich, descriptive vocabulary)

4) scientific texts (includes texts such as medical reports, legal texts, academic journals, etc)

5) informational texts (texts that are used to convey information to readers, such as technical guides, costumer guides, textbooks)

6) poetic texts. because they are essays, short stories, poems, etc.
