input: CHAPTER XXXI. AN INTERLUDE 

It was close on midnight now, and still they sat opposite one another, he the friend and she the wife, talking over that brief half-hour that had meant an eternity to her. 

Marguerite had tried to tell Sir Andrew everything; bitter as it was to put into actual words the pathos and misery which she had witnessed, yet she would hide nothing from the devoted comrade whom she knew Percy would trust absolutely. To him she repeated every word that Percy had uttered, described every inflection of his voice, those enigmatical phrases which she had not understood, and together they cheated one another into the belief that hope lingered somewhere hidden in those words. 

"I am not going to despair, Lady Blakeney," said Sir Andrew firmly; "and, moreover, we are not going to disobey. I would stake my life that even now Blakeney has some scheme in his mind which is embodied in the various letters which he has given you, and which--Heaven help us in that case!--we might thwart by disobedience. Tomorrow in the late afternoon I will escort you to the Rue de Charonne. It is a house that we all know well, and which Armand, of course, knows too. I had already inquired there two days ago to ascertain whether by chance St. Just was not in hiding there, but Lucas, the landlord and old-clothes dealer, knew nothing about him."

input: In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number "x" to its square "x". The output of a function "f" corresponding to an input "x" is denoted by "f"("x") (read ""f" of "x""). In this example, if the input is −3, then the output is 9, and we may write . Likewise, if the input is 3, then the output is also 9, and we may write . (The same output may be produced by more than one input, but each input gives only one output.) The input variable(s) are sometimes referred to as the argument(s) of the function. 

Functions of various kinds are "the central objects of investigation" in most fields of modern mathematics. There are many ways to describe or represent a function. Some functions may be defined by a formula or algorithm that tells how to compute the output for a given input. Others are given by a picture, called the graph of the function. In science, functions are sometimes defined by a table that gives the outputs for selected inputs. A function could be described implicitly, for example as the inverse to another function or as a solution of a differential equation. 1. What are functions?
2. Between what?
3. What are different types of function in today's mathematics?
4. What sort of image could you use to describe them?
5. How could a function's representation be implied?
6. Any other way?
7. What way is that?
8. How could a function be directly defined?
9. Can each input give many outputs?
10. Can an output give many inputs? Return numbered answers in your output.

output: 1. relations
2. inputs and outputs
3. the central objects of investigation
4. a graph
5. as the inverse to another function
6. yes
7. a solution of a differential equation
8. by a table
9. no
10. yes


input: (CNN) -- While Rafael Nadal enjoys a fishing trip in his native Mallorca, Roger Federer is closing on his Spanish rival's No. 2 ranking and his Masters titles record after reaching the final in Madrid. 

Nadal, like Novak Djokovic, couldn't wait to get away from the controversial blue clay at the Caja Magica but Federer has made the best of the situation and thrashed Janko Tipsarevic 6-2, 6-3 on Saturday in a one-sided semifinal. 

Waiting in the final is Tomas Berdych, who beat a tetchy Juan Martin del Potro 7-6 (5), 7-6 (6) earlier in the day. 

Federer will move above Nadal in the rankings if he wins his third Madrid title, and will also equal the Spaniard's record of 20 Masters titles. 

"I didn't even know actually about the No. 2 ranking," Federer said. "I'm focused on what I am doing here this week, trying to play well and get on a bit of a roll and I have played better and better as the tournament went on." 

Tipsarevic had knocked out fellow Serb Djokovic a day earlier, taking advantage of his compatriot's dislike of the blue clay surface. 

But in a match watched by Real Madrid star Cristiano Ronaldo, Tipsarevic was no match for Federer, who hit 25 winners to take his head-to-head record over the Serb to 5-0. 

Federer's possible rise to No. 2 in the rankings is even more significant with the French Open looming. It means the 16-time Grand Slam champion could avoid playing Djokovic or Nadal until the final.  1. Rafael Nadal enjoys what ?
2. where ?
3. Roger Federer is closing on what ?
4. anything else ?
5. where did he reach the final ?
6. Federer will move above who ?
7. in what ?
8. Tipsarevic had knocked who ?
9. who hit 25 winners ?
10. what sport show is this ? Return numbered answers in your output.

output:
1. fishing trip
2. native Mallorca
3. Spanish rival's No. 2 ranking
4. Masters titles record
5. Madrid
6. Nadal
7. in the rankings
8. Serb Djokovic
