Error Spotting – Choose the single segment (A–D) that contains a grammatical or spelling error; select ‘‘All correct’’ only if the entire sentence is correct. Sentence: A) stationary B) items go into an inventory C) assiduously D) prepared

Introduction / Context:
This question targets a classic confusable pair: “stationary” versus “stationery.” The context clearly points to office supplies, not to something that is not moving. Recognizing such homophones is crucial in business English and administrative writing.

Given Data / Assumptions:

• Topic: items recorded in inventory.
• Modifier in A: “stationary” (meaning “not moving”).
• Intended sense: office supplies like paper, pens, files → “stationery”.

Concept / Approach:
Differentiate by meaning and mnemonic: “stationery” (E for Envelope) relates to writing materials; “stationary” (A for At rest) means not moving. Inventory management naturally concerns “stationery items.”

Step-by-Step Solution:
1) Determine semantic field: procurement and inventory of office supplies.2) Match the correct homophone: “stationery,” not “stationary.”3) Corrected sentence: “Stationery items go into an inventory assiduously prepared.”4) Select A as the error segment.

Verification / Alternative check:
Substitute synonyms: writing materials, office supplies. These align with “stationery,” confirming the needed correction.

Why Other Options Are Wrong:

• B: Clause structure is fine.
• C: “assiduously” (diligently) is correctly spelled and used.
• D: Past participle “prepared” is appropriate.

Common Pitfalls:
Relying on sound rather than meaning; forgetting the envelope mnemonic for “stationery.”

Final Answer:
stationary
