Which sentences in this excerpt from the time machine by h. g. wells suggest that the morlocks possess a degree of intelligence comparable to that of humans?
within was a small apartment, and on a raised place in the corner of this was the time machine. i had the small levers in my pocket. so here, after all my elaborate preparations for the siege of the white sphinx, was a meek surrender. i threw my iron bar away, almost sorry not to use it.

a sudden thought came into my head as i stooped towards the portal. for once, at least, i grasped the mental operations of the morlocks. suppressing a strong inclination to laugh, i stepped through the bronze frame and up to the time machine. i was surprised to find it had been carefully oiled and cleaned. i have suspected since that the morlocks had even partially taken it to pieces while trying in their dim way to grasp its purpose.

now as i stood and examined it, finding a pleasure in the mere touch of the contrivance, the thing i had expected happened. the bronze panels suddenly slid up and struck the frame with a clang. i was in the dark—trapped. so the morlocks thought. at that i chuckled gleefully.

i could already hear their murmuring laughter as they came towards me. very calmly i tried to strike the match. i had only to fix on the levers and depart then like a ghost. but i had overlooked one little thing. the matches were of that abominable kind that light only on the box.
