Identify the part (A–E) that contains a grammatical error in the sentence below. If there is no error, choose option E (No error). Sentence (split into parts): A) Generally, people have not receptive B) and fail to notice the C) irrelevant answers they D) get for straight questions.

Introduction:
The sentence tests adjective complementation and the correct choice of linking verb with predicate adjectives. The phrase "have not receptive" is ungrammatical because "receptive" is an adjective and must be linked to the subject with "be", not "have".

Given Data / Assumptions:

• Modifier "Generally" frames a general truth.
• Target phrase: "people have not receptive".
• Predicate adjective: "receptive".
• The rest of the sentence (B–D) forms a coherent clause about failing to notice irrelevant answers.

Concept / Approach:
Adjectives that describe a subject’s state take the copular verb "be": "people are not receptive". Using "have" would require a noun complement ("have no receptivity") or a direct object. Therefore, part A should read "Generally, people are not receptive".

Step-by-Step Solution:
1) Identify word class: "receptive" → adjective.2) Choose correct link verb: "are", not "have".3) Correct fragment: "Generally, people are not receptive".4) Confirm remaining parts: B–D are fine and logically continue the idea.

Verification / Alternative check:
Alternative noun-based version: "Generally, people have low receptivity…"—also grammatical, but it changes diction. The intended structure is adjectival.

Why Other Options Are Wrong:
B: Proper coordination.C: Noun phrase "irrelevant answers" is correct.D: Prepositional phrase "for straight questions" is idiomatic.

Common Pitfalls:
Confusing "have" + object with "be" + adjective. Many state descriptions require "be".

Final Answer:
A (Replace "have" with "are")
