ERROR SPOTTING — Identify the part (A–E) that contains a grammatical, usage, or spelling error. If there is no error, choose E (All correct). Sentence (split into parts): A) He was very kin B) to process all the C) available D) information

Introduction / Context:
This question tests a near-homograph pair: “kin” (relatives) vs “keen” (eager). The sentence refers to a person’s eagerness to process information.

Given Data / Assumptions:

• Structure: “be keen to + base verb” expresses eagerness.
• Segment A uses “kin”, which denotes family relations.
• Segments B–D are grammatically correct and coherent.

Concept / Approach:
The correct adjective in this idiom is “keen”, often intensified as “very keen to …”. “Kin” cannot serve as an adjective for eagerness in this context. Correcting the vowel changes the meaning to the intended one.

Step-by-Step Solution:
1) Recognize the idiom “be keen to do something”.2) Replace “kin” with “keen”.3) Full corrected sentence: “He was very keen to process all the available information.”4) Verify remaining segments for grammaticality (articles and noun usage are fine).

Verification / Alternative check:
Synonym test: “eager to process…” fits perfectly, confirming “keen”.

Why Other Options Are Wrong:
B) Correct infinitival complement.C–D) Standard noun phrase “the available information”.

Common Pitfalls:
Typographical errors that swap vowels and create different words (keen/kin, lose/loose).

Final Answer:
A (Write: “very keen”)
