When Rob became interested in electricity, his clear-headed father considered the boy's fancy to be instructive as well as amusing; so he heartily encouraged his son, and Rob never lacked batteries, motors, or supplies of any sort that his experiments might require.
He fitted up the little back room in the attic as his workshop, and from thence, a network of wires soon ran throughout the house. Not only had every outside door its electric bell, but every window was fitted with a burglar alarm; moreover, no one could cross the threshold of any interior room without registering the fact in
Rob's workshop. The gas was lighted by an electric fob; a chime, connected with an erratic clock in the boy's room, woke the servants at all hours of the night and caused the cook to give warning; a bell rang whenever the postman dropped a letter into the box; there were bells, bells, bells everywhere, ringing at the right time, the wrong time and all the time. And there were telephones in the different rooms, too, through which Rob could call up the different members of the family just when they did not wish to be disturbed.
His mother and sisters soon came to vote the boy's scientific craze a nuisance; but his father was delighted with these evidences of Rob's skill as an electrician and insisted that he be allowed perfect freedom in carrying out his ideas.

The author's purpose for the second paragraph is:

Paragraph three performs which of the following functions?

In conclusion, it seized first the corpse of the daughter, and thrust it up the chimney, as it was found; then that of the old lady, which it immediately hurled through the window headlong. As the ape approached the casement with its mutilated burden, the sailor shrank aghast to the rod, and, rather gliding than clambering down it, hurried at once home-dreading the consequences of the butchery, and gladly abandoning, in his terror, all solicitude about the fate of the Ourang-Outang.
The words heard by the party upon the staircase were the Frenchman's exclamations of horror and affright, commingled with the fiendish jabberings of the brute.
I have scarcely anything to add. The Ourang-Outang must have escaped from the chamber, by the rod, just before the break of the door. It must have closed the window as it passed through it. It was subsequently caught by the owner himself, who obtained for it a very large sum at the Jardin des Plantes. Le Don was instantly released, upon our narration of the circumstances (with some comments from Dupin) at the bureau of the Prefect of Police. This functionary, however well disposed to my friend, could not altogether conceal his chagrin at the turn which affairs had taken, and was fain to indulge in a sarcasm or two, about the propriety of every person minding his own business.
The word `solicitude` in 1st paragraph most nearly means
