Candidate passages:
ImLive performers are called "hosts" and are mostly amateur webcam models who earn money for their performances on the site.
Customers of the site can purchase virtual credits called ImLive credits, which are used to pay for all services provided through the website.
They can also be used to tip hosts or watch private shows.
Hosts charge a varying amount of credits for video chat, ranging from approximately 1 to 6 ImLive credits per minute.
Credits are sold in multiples of 25.
Customers can use text based live chat to talk to each other or in each host's channel.
The hosts use a webcam and microphone to broadcast live video and audio to their channel.
Both members and hosts can send private messages and mail to each other.
In 2010, ImLive launched ImLive Mobile, allowing features including video chat on smartphones.---- Host earningsHosts earn 30% of what customers pay including tips.
For example, if a customer pays $20 for a vchat session or tip, Imlive earns $14 and the host earns $6.
Also, hosts are required to perform hours of "free live chat" in which they are not paid.
Hosts meet potential customers there but do not receive any payment unless the customer goes to a paid video chat session. 
The last challenge that is used on each episode is called "The Final 19 Yards".
The one surviving contestant has to answer five questions, each worth an increasing value of money.
The first question is worth £5,000, the second is worth £10,000, the third is worth £20,000, the fourth is worth £50,000 and the final question earns the jackpot of £100,000.
On each question, the contestant is read out a series of clues that leads them to the answer.
After the first clue is read out, the buzzer begins to move down the 19 yard track from the start when the first question is played and from then on, where it left off.
Once the contestant thinks they know what the answer is, they can make the run up to hit the buzzer, a correct answer earns them that value of money the question is worth but if they give a wrong answer, they go back down to the value of the last question and leave with that amount and if the buzzer reaches the end of the 19 yards before they either give a wrong answer or decide to take the money, they lose everything they have earned to that point and leave with nothing.
Playing the first question is compulsory but after then, they can decide to play the next question or stop and take the money. 
The format is based on the syndicated changes to fellow Twentieth Television game show "Are You Smarter Than a 5th Grader?".
One contestant plays the entire show, with one song each from four different categories.
They are then given a choice of two different songs.
Each time a contestant answers a song correctly, he/she earns money; if he/she misses a song, except for the Encore Song, those winnings remain intact.
There is also only one "backup"; the three lines, which may only be used once. 
"Their power is too great...their madness, even greater".
"If you are ever to destroy evil, you must survive to fight it".
"In the end, it is usually the good mind who enables evil to thrive".
"You did what you had to do...perhaps, that is the most subtle definition of bravery".
Stocker: "We didn't earn your thanks".
Grippians: "The mind earns by doing...the heart earns by trying". 
Banks generally borrow the money they then lend to their customers.
As they receive very low-interest loans from other firms, they may borrow as much as their customers require, while lending their capital to other borrowers at higher rates.
If the card issuer charges 15% on money lent to users, and it costs 5% to borrow the money to lend, and the balance sits with the cardholder for a year, the issuer earns 10% on the loan.
This 10% difference is the "net interest spread" and the 5% is the "interest expense".
