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

Input: Consider Input:  ['Give the cells owner a flow of electricity.', 'Adding an external circuit allows the exchange to continue', 'This produces an electric field that allows electrons to flow from negative to positve', 'A photovoltaic cell is created with two layers of semiconductor material', 'Sunlight enters the cell', 'Energy from sunlight knocks electrons loose in both fields', 'The top layer are &#x27;doped&#x27; with impurities to allow a negative charge', 'The bottom layer are &#x27;doped&#x27; to allow for a positive charge', 'This prevents the flow of electrons from negative to positive'] 

Output:   No  


Input: Consider Input:  ['The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms', 'It will turn into either petroleum or natural gas', 'Over time, more sediment piles on top', 'Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand', 'Left alone, the kerogen molecules eventually crack', 'The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen'] 

Output:   No  


Input: Consider Input:  ['Water is absorbed through roots', 'Oxygen gets released into atmosphere', 'Hydrogen and carbon dioxide used to create glucose', 'Energy splits water molecules into hydrogen and oxygen', 'Carbon dioxide passes through stomata in the leaves', 'Glucose is food for plants.', 'Chlorophyll absorbs energy from sunlight', 'Chloroplast cells in leaves contain chlorophyll'] 


Output:   No
