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

SOLUTION: No

PROBLEM: ['Minerals form when magma and lava cool', 'Melted rock inside the Earth is also called molten rock, or magma', 'There are places inside Earth where rock will melt', 'When magma erupts onto Earth's surface, it is known as lava', 'Magma moves up through Earth's crust, but it does not always reach the surface', 'As lava flows from volcanoes it starts to cool']

SOLUTION: No
