This question tests your understanding of verb patterns and causative structures in English grammar. Let's break it down step-by-step.

Step 1: Analyzing the First Blank

The first sentence is: "Your hair needs _____, doesn't it?"

The verb 'need' can be followed by two structures:

• Need + to-infinitive (active voice): e.g., "I need to cut my hair."
• Need + gerund (-ing form) (passive meaning): e.g., "My hair needs cutting." (which means "My hair needs to be cut")

Since the subject is "Your hair" (an object, not a person performing an action), the gerund form with a passive meaning is the most appropriate. Therefore, the first blank should be filled with 'cutting'.

Step 2: Analyzing the Second Blank

The second sentence is: "Yes, I'm getting it _____ this weekend."

This sentence uses a causative structure.

The pattern is: Get + Object + Past Participle. This structure is used to say that you arrange for someone else to do something for you.

Example: "I'm getting my car washed." (I am arranging for someone to wash my car).

Therefore, for the verb 'cut', the past participle is 'cut'. The correct phrase is "getting it cut".

Final Answer

Based on this analysis, the correct option is the one that uses "cutting" for the first blank and "cut" for the second.

Correct Choice: cutting / cut

The full, correct dialogue is:
A: Your hair needs cutting, doesn't it?
B: Yes, I'm getting it cut this weekend.

Verb Patterns: Many verbs in English are followed by specific structures, like gerunds or infinitives. Memorizing these patterns is key. For example, 'enjoy' is always followed by a gerund (I enjoy reading), while 'decide' is followed by an infinitive (I decided to leave).

Causative Verbs (Get/Have):

• Get/Have + Object + Past Participle: Used to express that you caused something to be done by someone else.
  • I had my suit cleaned.
  • She got her passport renewed.
