It looks like you made some good corrections! Here's a breakdown of each one:

1) The pilgrims arrived from different parts of society. Correction: The pilgrims belong to different social classes.
Correction: The correction you made is accurate. You changed "parts of society" to "social classes," which better conveys the meaning.

2) The tales were never completed/finished. Correct
Correction: Since "completed" and "finished" are both acceptable, your correction is correct.

3) As a way for passing the time (correction: as a way of passing the time)
Correction: You changed "for" to "of", which is the correct form in this phrase.

4) She made attention not to make mistakes. Correction: she was careful/she paid attention/not to make mistakes.
Correction: You provided multiple alternatives to correct the sentence. Each option works, so it depends on the context and style you prefer.

5) The tales are composed by rhyming couplets. Correction: they are composed of/they consist of ....
Correction: You changed "by" to "of" or "consist of", both of which are correct options and convey the intended meaning.

6) She spoke a good French. Correction: she could speak good French.
Correction: Your correction changes "spoke" to "could speak," which is a more accurate way to express past ability.

7) Thomas Becket is one of the most venerated saints of England. Correction: in England.
Correction: Your correction is accurate. You changed "of" to "in" to specify the location where Thomas Becket is venerated.

8) There will be a prize for who tells the best story. Correction: a prize for the one who tells the best story.
Correction: Your addition of "the one" clarifies that the prize is for an individual, which improves the sentence.

9) Finally, Chaucer tells about Zephyrus. Finally, Chaucer describes Zephyrus.
Correction: Your alternative correction changes "tells about" to "describes," which better conveys how Chaucer presents Zephyrus.

10) The prologue is in April. Correction: the prologue is set in April.
Correction: Your correction changes "is in" to "is set in," which accurately describes the time frame of the prologue.

11) The aristocracy is not present in Chaucer's portrait of English society. Correct
Correction: No correction needed. Your statement is correct as it is.

12) She cared for appearance or appearances?
Correction: The correct phrase is "She cared for appearances" because it refers to the general concept of someone's overall appearance.

13) He wants to communicate the reader the things he doesn't agree with the character. Correction: the things he doesn't approve of in the character.
Correction: Your correction changes "agree with" to "approve of," which more accurately conveys the desired meaning.

14) In his description of English society he didn't talk about the peasants. Correction: he didn't mention the peasants.
Correction: Your correction changes "talk about" to "mention," which better describes the level of attention given to the topic.
