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:  ['Chloroplasts in the leaf of the plant traps light from the sun', 'The roots absorb water and minerals from the soil', 'This combination of water and minerals flows from the stem into the leaf', 'Carbon dioxide enters the leaf', 'Light, water and minerals, and the carbon dioxide all mix together', 'This mixture forms sugar (glucose) which is what the plant eats', 'Oxygen goes out of the leaf through the stomata'] 

Output:   Yes  


Input: Consider Input:  ['Contact is made with a virus', 'The virus enters the human or animal body', 'The virus goes to the part of the body that contains its food', 'The virus consumes part of the body or materials that the body uses', 'The virus replicates and spreads', 'The virus causes symptoms in the body as the immune system tries to expel the virus.'] 

Output:   Yes  


Input: Consider Input:  ['Light energy is absorbed by chlorophyll in a plant', 'The light energy is used to convert carbon dioxide', 'The plant uses nutrients in the soil', 'The plant uses carbon dioxide in the air to produce glucose', 'The plant uses the glucose to give itself energy', 'Oxygen is released as a by product.'] 


Output:   Yes
