In the following paragraph, which portion is the topic sentence?
Keeping a pet requires dedication and
selflessness; it is not a decision which should be
considered lightly, and one needs to take into
account all the responsibilities involved before
making the commitment. For example, fish tanks
need to be washed out on a weekly basis,
hamster cages need to be cleaned out regularly,
and dogs need to be walked daily. Moreover,
animals need constant love and affection, and
one's lifestyle will need to be adjusted when
accommodating a pet. Consequently, there are
many factors which need to be weighed up
before making such a commitment.

Explanation:

"Keeping a pet requires dedication and selflessness"

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
