Correct : English Grammar

The sentence describes Mr. X falling while trying to collect an envelope and then losing consciousness. We need to identify the part that is not appropriate.
Analyze Each Underlined Part:
(I) "collect": "Collect" is appropriate because Mr. X is retrieving an envelope. This part is correct.
(II) "from under the table": This correctly describes where the envelope is located. This part is correct.
(III) "fell down": "Fell down" is the correct simple past form and appropriately describes what happened to Mr. X. This part is correct.
(IV) "was losing consciousness": This is not appropriate in this context. The more appropriate expression is "lost consciousness." Therefore, this part is incorrect.
Correct Answer: D) IV
