Teacher:You will be given two pieces of text with the same meaning. One of them is simpler and easier to understand for non-native English speakers. Complex texts may contain more difficult words, have unnecessary phrases or contain long sentences. Your task is to choose the simpler piece of text. You are expected to output 'Text one' if the first sentence is simpler. Otherwise output 'Text two'.
Teacher: Now, understand the problem? Solve this instance: Text one: In practice, however, the definition means that high-precision realizations of the second should compensate for the effects of the ambient temperature (black-body radiation) within which atomic clocks operate, and extrapolate accordingly to the value of the second at a temperature of absolute zero.
 Text two: It means that high-precision calculations of the second should make up for the ambient temperature effects. Atomic clocks operate and extrapolate in these effects. It happens to the value of the second at absolute zero.
Student:
Text two
