Question

select the correct answer from the drop - down menu. look at the underlined details in paragraphs 12 and 13. (12) he sat up, took the spoon full of treacle, and poured the powder as usual into the very middle of it. i watched him take it off at a single gulp without perceiving the difference, and then i sank back exhausted upon my roll of sealskins. (13) all that day i was very ill; and lemarchant, lying tossing beside me, groaned and moaned in a fearful fashion. at last the truth seemed to dawn upon him gradually; and he cried aloud to me: \doctor, doctor, quick, for heaven’s sake! you must get me an antidote. the powders must have got mixed up somehow; and you’ve given me arsenic instead of quinine, i’m certain.\ these details use order of events to create tension as drop - down menu options: lemarchant receives help from the narrator to fight the effects of the arsenic, lemarchant realizes that his plan to poison the narrator has backfired, the narrator becomes exhausted and uninterested in lemarchant, the narrator watches as his plan to poison lemarchant fails

Explanation:

In paragraph 12, the narrator watches Lemarchant take the mixture. In paragraph 13, Lemarchant realizes he was given arsenic (poison) instead of quinine (the intended antidote or medicine), meaning his plan to poison the narrator backfired as he ended up being poisoned. The option "Lemarchant realizes that his plan to poison the narrator has backfired" matches this sequence of events: he took the mixture (narrator watched), then realized the powder was arsenic (his poisoning plan against the narrator went wrong as he got poisoned). Other options don't fit: he didn't receive help to fight arsenic effects, the narrator didn't become exhausted/uninterested, and the narrator isn't watching a plan to poison Lemarchant fail (it's Lemarchant's own plan against the narrator that backfired).

Answer:

Lemarchant realizes that his plan to poison the narrator has backfired
