In this task, you will use your knowledge about language (and common sense) to determine what element the marked number refers to. The numbers are marked with two underlines around them, like: _ number _. Your answer should be chosen from the given text, and should not contain other words.

Example Input: Commissioner Gordon:  You two will never get away with this !
Egghead: Oh really , Commissioner , I wish someone would write you a new line , that _ one _ is getting so tired .
Example Output: line

Example Input: Lady Bracknell:  Come on , Gwendolyn , we have already missed _ five _ , if not six trains ! To miss any more might expose us to comments on the platform .
Example Output: trains

Example Input: Wizard:  So , Superman 's feats and skills are definitively measured . However , Goku 's are not and are difficult to judge . Not only does Dragonball heavily abuse cinematic time , but Goku 's final adventures in Dragonball GT are incredibly inconsistent due to his untimely transformation into a child . As ki is dependent on the physical body , his child form likely could not handle his own ki , sending his power into flux .
Boomstick: And obviously , we 're not using future Goku 'cause that would require a ridiculous amount of assumption . Not to mention we 'd have to use future Superman , who 's pretty much God . So , like Superman , we need to judge Goku in his prime .
Wizard: After experimenting with dozens of different theories , we discovered an iron - clad method to finding Goku 's limits , which we call the Gravity Formula , based around his training in increased gravity . Due to his style of training and Saiyan heritage , Goku increases his abilities proportionate to the amount of force he trains under . While in base form , Goku could lift just under 40 tons . This is equivalent to 586x normal Earth gravity , which we will use in the Gravity Formula along with the Super Saiyan multipliers to calculate Goku 's maximum potential .
Boomstick: Multiplying the 40 tons by the Super Saiyan forms means he can lift up to 160000 tons in Super Saiyan 4 , strong enough to pick up a continent ... or my ex - wife . Ha ha ! Right after Goku trained on King Kai 's planet , which has gravity 10x stronger than Earth 's , he flew across Snake Way Road as fast as possible to save his friends . It took him 28 hours , impressive since that 's 1000000 kilometers long .
Wizard: Except it 's filled with curves and Goku flew straight over it , so how far did he actually travel ? By comparing Goku 's height to a single spike , we can measure each curve . We can then remove those curves from the overall length . So it turns out that Goku actually flew 307000 kilometers , nearly 11000 km / h .
Boomstick: To see how fast his base form is at the end of the series , we run the Snake Way number through the gravity formula to find that his top speed clocks in at over 2 1/2 billion km / h , over 2x the speed of light .
Wizard: We can determine Goku 's durability through this bomb , which the brilliant Dr. Gero designed to kill Goku at age 25 , when his maximum potential was Kaio - Ken x4 .
Boomstick: Scans of the bomb display a TNT measurement of _ 657 _ . Bulma says the bomb could destroy the Earth , so this is likely measured in quadrillion megatons , since it takes at least 53 quadrillion megatons of force to destroy the Earth .
Wizard: So in his final form , Goku can survive up to nearly 35 sextillion megatons .
Boomstick: Goku does n't rely solely on his physical abilities . He amplifies his strength and durability with ki .
Wizard: But even though his ki reserves can not be measured , we can determine his maximum output . See , his ki attacks do not force him backward unless he allows them to .
Boomstick: Even when firing upward at full power , the ground beneath him remains untouched .
Wizard: Therefore , according to physics , his maximum output is at most equal to the amount of force he can withstand .
Boomstick: Luckily , we just calculated that with the Gero bomb .
Example Output:
measurement
