Question

How does the author's diction affect the tone of the text?

The use of slang words creates a relaxed, informal tone.
The use of academic language creates an angry and disdainful tone.
The use of academic language gives the text a serious and instructive tone.
The use of words with strong connotative meanings creates a sorrowful tone.

Answer 1

"The use of academic language gives the text a serious and instructive tone."

Reason: diction shapes tone—slang makes writing informal; academic/technical diction tends to make it formal, serious, and instructive. Academic language does not inherently create anger or disdain, and words with strong connotations can produce many tones (sorrowful only if the connotations are sad).
