This question tests the difference between adjectives ending in "-ed" (bored) and "-ing" (boring).

Concept: In English, we use "-ed" adjectives to describe a person's feelings. We use "-ing" adjectives to describe the thing or person that causes the feeling.

• -ed adjectives (e.g., bored, tired, excited): Describe how someone feels.

  Example: "I am bored." (This describes my feeling.)

• -ing adjectives (e.g., boring, tiring, exciting): Describe the quality of something that causes a feeling.

  Example: "This movie is boring." (This describes the movie's quality, which causes the feeling of boredom.)

Step-by-Step Solution:

Step 1: Analyze the first blank: "Are you _______?" This question is asking about a person's feeling. Therefore, we need an "-ed" adjective. The correct word is bored.

Step 2: Analyze the second blank: "Or is the book _______?" This question is asking about the quality of the book (a thing). Therefore, we need an "-ing" adjective. The correct word is boring.

Final Answer: The sentence should be: "Are you bored? Or is the book boring?"

This means: "Are you (feeling the emotion of boredom)? Or is the book (the thing causing the boredom)?"

Topic: Participial Adjectives

Theory: Many adjectives are formed from verbs. The present participle (verb + -ing) and the past participle (verb + -ed) can both be used as adjectives, but with different meanings, as explained above. There is no mathematical formula, but a simple rule to remember:

Feeling (Experienced) → use -ed
Cause (Creating the feeling) → use -ing
