[Q]: CHAPTER IV. 

Signor Andrea D'Arbino, searching vainly through the various rooms in the palace for Count Fabio d'Ascoli, and trying as a last resource, the corridor leading to the ballroom and grand staircase, discovered his friend lying on the floor in a swoon, without any living creature near him. Determining to avoid alarming the guests, if possible, D'Arbino first sought help in the antechamber. He found there the marquis's valet, assisting the Cavaliere Finello (who was just taking his departure) to put on his cloak. 

While Finello and his friend carried Fabio to an open window in the antechamber, the valet procured some iced water. This simple remedy, and the change of atmosphere, proved enough to restore the fainting man to his senses, but hardly--as it seemed to his friends--to his former self. They noticed a change to blankness and stillness in his face, and when he spoke, an indescribable alteration in the tone of his voice. 

"I found you in a room in the corridor," said D'Arbino. "What made you faint? Don't you remember? Was it the heat?" 

Fabio waited for a moment, painfully collecting his ideas. He looked at the valet, and Finello signed to the man to withdraw. 

"Was it the heat?" repeated D'Arbino. 

"No," answered Fabio, in strangely hushed, steady tones. "I have seen the face that was behind the yellow mask." 

"Well?" 

"It was the face of my dead wife." 

"Your dead wife!" 

"When the mask was removed I saw her face. Not as I remember it in the pride of her youth and beauty--not even as I remember her on her sick-bed--but as I remember her in her coffin." 
[A]: Who was searching in vain?


[Q]: My dad runs the Blue Street Zoo. Everyone calls him the Zoo King. That means Mom is the Zoo Queen. And that means that I'm the Zoo Prince! Being a prince is very special. 

I spend every morning walking around to see the zoo. It's better than any animal book. I say hello to the lions. I say woof at all of the wolves. I make faces to the penguins. Once I even gave a morning kiss to a bear! My favorite animal is the piggy. I named him Samson. He likes to eat mustard, so I toss some mustard jars into his cage every morning. I don't know why that piggy likes mustard so much. 

Sometimes I walk around with the Zoo King and Zoo Queen. Then we say hello to the animals together! I really like those days. Everybody who works at the Zoo says hello to us when we walk by. At lunchtime, we all go to the Zoo restaurant and eat pork chops. I hope Samson doesn't get mad about that!
[A]: Who runs the zoo?


[Q]: CHAPTER XII. 

Madame Colonna, with that vivacious energy which characterises the south, had no sooner seen Coningsby, and heard his praises celebrated by his grandfather, than she resolved that an alliance should sooner or later take place between him and her step-daughter. She imparted her projects without delay to Lucretia, who received them in a different spirit from that in which they were communicated. Lucretia bore as little resemblance to her step-mother in character, as in person. If she did not possess her beauty, she was born with an intellect of far greater capacity and reach. She had a deep judgment. A hasty alliance with a youth, arranged by their mutual relatives, might suit very well the clime and manners of Italy, but Lucretia was well aware that it was altogether opposed to the habits and feelings of this country. She had no conviction that either Coningsby would wish to marry her, or, if willing, that his grandfather would sanction such a step in one as yet only on the threshold of the world. Lucretia therefore received the suggestions and proposals of Madarne Colonna with coldness and indifference; one might even say contempt, for she neither felt respect for this lady, nor was she sedulous to evince it. Although really younger than Coningsby, Lucretia felt that a woman of eighteen is, in all worldly considerations, ten years older than a youth of the same age. She anticipated that a considerable time might elapse before Coningsby would feel it necessary to seal his destiny by marriage, while, on the other hand, she was not only anxious, but resolved, not to delay on her part her emancipation from the galling position in which she very frequently found herself. 
[A]:
How old is Lucretia?
