Read the excerpt below from Moby-Dick by Herman Melville:
"Who-e debel you?"—he at last said—"you no speak-e, dam-me, I kill-e."
[...]
"Don't be afraid now," said he, grinning again. "Queequeg here wouldn't harm a hair of your head."
[...]
"Me sabbee plenty," grunted Queequeg, puffing away at his pipe and sitting up in bed.
Read the statements below carefully:

I.Queequeg's speech demonstrates a limited command of English grammar and vocabulary.

II.The landlord's statement "Don't be afraid now" performs the social function of reassurance.

III.The expression "wouldn't harm a hair of your head" is used to communicate that Queequeg poses no threat to Ishmael.

IV.The phrase "Me sabbee plenty" illustrates a standard grammatical structure commonly found in formal English.

V.The interaction reveals an initial communication barrier between the characters.
