Answer:
Independent clauses linked without a conjunction - Hang gliding is a popular pastime; it takes skill and a bit of daring.
An introductory participial phrase - Walking without a cane, the old man tried to escape unnoticed.
A mark indicating that a list will follow - These colors were chosen for the school: purple, green, and white.
A comma linking two independent clauses - Christ was equal with God, but He willingly became a servant.
A sentence demonstrating direct address - You seem to have found, my good friend, a real peace in life.
Step-by-step explanation:
When a sentence consists of multiple independent clauses, they need to be connected by a conjunction preceded by a comma or a semicolon (like in the sentence: Hang gliding is a popular pastime; it takes skill and a bit of daring.)
Introductory participial phrases are phrases that contain participles and are located at the beginning of the sentence. Participles are forms of verbs used as adjectives. They end in -ed, -ing or -en.
The mark that indicates that a list will follow is the colon.
Direct address involves the use of a person's name or title to address that person directly.
