Read these lines: "Unable to endure the aspect of the being I had created, I rushed out of the room and continued a long time traversing my bed-chamber, unable to compose my mind to sleep. At length lassitude succeeded to the tumult I had before endured, and I threw myself on the bed in my clothes." As used in the quoted lines, the word "lassitude" most nearly means

1. 1. Before the word, he is pacing for a long time and cannot compose his mind, which is exhausting. 2. 2. The word succeeded to the tumult, so it names whatever replaced that agitation. 3. 3. What he does next is throw himself on the bed still dressed, which is the act of a worn-out man. 4. 4. Fresh energy and anger would keep him pacing, and joy fits nothing in the lines, so weariness is the meaning. _Source: Frankenstein by Mary Shelley (1818)_
