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 seeds are dispersed by wind, animals, etc', 'The seeds reach the ground', 'Grow into new trees', 'The process repeats itself over and over', 'A tree produces seeds', 'These new trees produce seeds'] 
Example output: No
Example explanation: These steps are not in order. The first step in this sequence is 'The seeds are dispersed by wind, animals, etc' but the step introducing the seed 'A tree produces seeds' is after the steps referencing the seeds. Therefore, the answer is No
