Input: Consider Input: Context: Biologists agree that the ancestor of mitochondria was an alpha-proteobacterium. But there is no consensus as to what constitutes an alpha-proteobacterial gene. Is it a gene found in all or several alpha-proteobacteria, or in only one? Here, we examine the proportion of alpha-proteobacterial genes in alpha-proteobacterial genomes by means of sequence comparisons. We find that each alpha-proteobacterium harbours a particular collection of genes and that, depending upon the lineage examined, between 97 and 33% are alpha-proteobacterial by the nearest-neighbour criterion. Our findings bear upon attempts to reconstruct the mitochondrial ancestor and upon inferences concerning the collection of genes that the mitochondrial ancestor possessed at the time that it became an endosymbiont. 
 Question: Which species of bacteria did the mitochondria originate from?

Output: biologists agree that the ancestor of mitochondria was an alpha-proteobacterium.


Input: Consider Input: Context: Hello, Listeners. Welcome to Henton Hospital Radio. Before our music programme at four, I'm going to repeat some of our hospital rules. The hospital can sleep 800 patients. There're 8 beds in each ward . The visiting hours are in the afternoon from 2:30 to 3:30 and in the evening from 7:00 to 8:00. But remember only two people can see you at the same time. Sorry about that, but you can see what would happen if we didn't have these rules. The other rules are about our hours. We start quite early---you might not be used to that. We wake you at 6 o'clock, and breakfast is at 8 o'clock, lunch is at noon. There's tea at 3:30 and supper is at 6 o'clock. You can see the non-smoking sign---we don't allow smoking in the wards. I'm sure you understand why. However, if you do need to smoke, there are some smoking rooms where it is allowed. You will find the radio switch on the wall near your bed, with your own headphones, if you want to listen. It's our own hospital radio wishing you a quick recovery. 
 Question: Who do you think the listeners might be?

Output: patients.


Input: Consider Input: Context: The film opens with an animated prologue revealing the origins of leprechauns, stating that they were summoned by a king to protect his gold from those who would try to steal it. After the death of the king the Leprechauns returned to their places of origin, all except one (Warwick Davis) who remained in the mortal world and through the ages slowly became corrupted and obsessed with the treasure he still guarded. In the present Father Jacob (Willie C. Carpenter) is chased through the construction site of the youth center he had planned on building by the Leprechaun, whose gold Jacob had taken to fund the building project. Using four-leaf clover laced holy water Jacob manages to banish the Leprechaun, summoning demonic hands which drag him underground, but soon after drops dead of injuries inflicted by the Leprechaun during the fight.One year later two down on their luck friends Emily Woodrow (Tangi Miller) and Lisa Duncan (Sherrie Jackson) have their fortune told when the clairvoyant Esmeralda (Donzaleigh Abernathy) who warns them that they will attain great wealth soon, but it must be denied as it will come at a great price and summon a terrible evil. While having a barbecue at the abandoned youth center construction site with Lisa, their stoner friend Jamie Davis (Page Kennedy) and her ex-boyfriend turned drug dealer Rory Jackson (Laz Alonso) Emily falls through a hole and discovers the Leprechaun's gold in an old tunnel where it was hidden by Father Jacob. Splitting up the gold (which is produced in a never ending amount by the chest it was contained in) evenly the quartet of friends use it to fulfill their fantasies, unaware that by taking the gold they have released the Leprechaun, who begins stalking the group (killing a guest who takes one of his coins at a party held by Jamie, prompting the police to temporarily arrest him). At the salon where Emily works the Leprechaun sneaks in and, after killing a regular customer, Doria, on the massage table by breaking her neck, attacks Emily, who barely escapes and warns Rory and the recently released Jamie, who rush to get to Lisa's. In her house Lisa is attacked by the Leprechaun and manages to fight him off for a short while, but is killed when the Leprechaun claws her in the stomach, with her friends finding her body moments later.While Emily and Jamie want to return the gold Rory does not and takes off with it; shortly after realizing Rory is gone Emily is attacked and chased outside by the Leprechaun, but is saved when Rory has a change of heart and comes back for her. Searching for Rory the Leprechaun stops by his house and kills Rory's profligate girlfriend Chanel (Keesha Sharp) by tearing out her upper jaw, reclaiming the gold she used to make a tooth while Rory and Emily are stopped and harassed by Officers Thompson (Beau Billingslea) and Whitaker (Chris Murray). After the Leprechaun appears and kills the two officers Emily and Rory escape and regroup with Jamie, only to be confronted by a machine gun wielding group of Rory's drug dealing rivals, led by Watson (Shiek Mahmud-Bey) and Cedric (Sticky Fingaz). Planning on executing Rory for infringing on their territory Watson and his gang are all disposed of by the Leprechaun, (who kills Watson and Cedric while the other two members run off) while Emily, Rory and Jamie drive off in Watson's car (which the Leprechaun latches to the bottom of for a short while) and go looking for help from Esmeralda.Advised to use four-leaf clovers against the Leprechaun by Esmeralda, Rory laces the hollow-point bullets of his gun with clovers Jamie finds in the marijuana Rory had earlier sold him. When the Leprechaun arrives Rory shoots him several times with the clover bullets, only for his gun to jam before he can finish the Leprechaun off. Rory and Emily are given the chance to run with the gold when the Leprechaun is distracted by Jamie and Esmeralda (the latter dying in a magical duel with the Leprechaun). Followed to the roof of the building Rory tries fighting the Leprechaun and is knocked out, though before the Leprechaun can kill him
