Step 1: Understanding the Concept
The question asks to identify the function or purpose of the given sentence. This involves understanding pragmatic meaning (what the speaker is trying to do). Step 2: Analyzing the Sentence Structure
The sentence starts with "Shall we...". This is a common grammatical structure in English used to make a suggestion or proposal to a group that includes the speaker. Step 3: Evaluating the Options
(A) suggesting: To put forward an idea or plan for consideration. "Shall we go for a movie?" fits this perfectly. The speaker is proposing an activity.
(B) requesting: To politely ask for something. A request would be phrased differently, like "Can you please go to a movie with me?".
(C) complaining: To express dissatisfaction or annoyance. This sentence expresses no negative feeling.
(D) apologising: To express regret for something one has done wrong. This sentence is not an apology. Step 4: Final Answer
The function of the sentence "Shall we go for a movie?" is to make a suggestion. Therefore, option (A) is correct.
