Read the excerpt from Ralph Waldo Emerson's essay entitled "Experience."
The least activity of the intellectual powers redeems us in a degree from the conditions of time. In sickness, in languor,
give us a strain of poetry, or a profound sentence, and we are refreshed; or produce a volume of Plato, or Shakspeare,
or remind us of their names, and instantly we come into a feeling of longevity. See how the deep, divine thought
reduces centuries, and millenniums, and makes itself present through all ages.
According to Emerson, which of these is immune to time?
o intellectual activity
sickness
physical activity
O memory
