question 1 options:

introduction

b)

eulogy

c)

special occasion

A ceremonial speech is a kind of special occasion speech.

This speech is generally given by an important person in a community to highlight the values and the beliefs of the members of a community. This speech refers to  important events for the life and well-being of a community. Therefore, when something important happens, this special occasion calls for a meeting and a ceremonial speech is given.

These options are wrong:

a) introduction: If there is a ceremony, the speaker will not give an introduction to a scientific speech or a story. He / She will make people think about community values.

b) eulogy: this is a speech given when someone has died.

to eliminate ambiguous remote or broad reference it is necessary to focus on anaphoric reference. by definition "anaphoric reference means that a word in a text refers back to other ideas in the text for its meaning." the references should be clear and leave no room for ambiguity.

in sentence number   two   the pronoun he refers to charles dickens the author. yet, the first half of the sentence is about the book a tale of two cities. to repair this it would be better to rephrase the first half : after i read   a tale of two cities by dickens, he so as to remove the remote reference.
