Pls! what would a good thesis statement be for a speech about tchaikovsky's life with the three main points of his early life, his adult life, and his death and legacy. (it's to inform btw) (or at least an idea of how i can form it all together)

You should map out what you are going to write about in your body paragraphs (pre-writing, outline, four-square).  What are the main points in each paragraph that could help you to form the statement?  Once you have that, it should make writing the thesis statement a bit easier.  If this is just a general overview, you could write something like, "Tchaikovsky's composition was shaped by many events that occurred early in life, during his adult life, and long after he passed away."  Again, it would largely depend on what you want your reader to know about the paragraphs they are about to read.

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.

the tone of the passage is sympathetic to the forbidden love of romeo and juliet. the nurse plays a significant role in the play. she is responsible for making their meeting again possible. additionally, there is a sense of warning in the choice of words of the nurse. she seems to be authoritative when she calls romeo "scurvy knave", and at the same time the fact that she addresses to him as "sir" reflects respect. the nurse is "vexed", this word describes her confused state of mind. on the one hand, she finds romeo a fine and eloquent man, but on the other, it is thought that man's nature forces men to try to trick women.
