Answer to Question 1

TRUE
Capitalize the first word following a colon if it begins a complete sentence requiring special
emphasis or if it begins a sentence stating a formal rule. Colons make readers pause and take
note of what follows.

Answer to Question 2

TRUE
When using consecutive adjectives in writing, no comma follows the last adjective in a
seriesthat is, no comma separates the last adjective from the noun. Consecutive adjectives
are adjectives that come together but separately modify a noun.
