You need to answer the question 'Are the given steps in order?', given a set of steps describing a process. Your answer must be either Yes or No. If the answer is No, that means the steps are out of order and do not make sense in the order they are in. If the answer is Yes, that means the steps are in order and make sense in the order that they are in. A set of steps are not in order if the steps reference information that is introduced in a later step

Example Input:  ['The nuclei of some atoms have too few or too many neutrons', 'The atoms become unstable', 'The atoms split', 'In alpha decay, two protons and two neutrons are released from the atom', 'In beta decay, a neutron changes into a proton and an electron', 'The proton joins the nucleus of the atom', 'The electron is released'] 
Example Output:   Yes  

Example Input:  ['Owls hunt around their hunting territory away from where they roost during the day', 'They sit still on a perch, like a stump of branch, and wait for prey', 'They use their highly sensitive hearing to locate prey that cannot be seen', 'They use their very keen vision to see prey in the dark', 'They fly silently, without flapping their wings, in order to surprise the prey', 'The owl silently glides or drops on its prey, grabbing it with its talons and beak', 'The owl eats the prey, or carries it back to its perch'] 
Example Output:   Yes  

Example Input:  ['The sediment rolls down hill towards a river', 'The heavy items sink to the bottom', 'Sediment becomes loose from the rest of the soil', 'The sediment gets dumped through tributaries into lakes and the ocean', 'The lighter items float on the top and in convection cycles', 'As the river flows the sediment is moved', 'The sediment keeps moving around the world in convection currents.'] 
Example Output:
  No
