In this task, you are given a paragraph, and your task is to construct a question from the given passage. Construct question in such a way that (i) it is well explained in the paragraph, (ii) the words may/may not be present in the paragraph, (iii) it should start with what/how/describe. Avoid creating a question that (i) is just relevant to one or two sentences, and (ii) not relevant to passage.

Q: You breathe in. Diaphragm and other muscles expand to allow room for your lungs to fill. The air flows into the narrow bronchioles in the lungs. From the bronchioles to the alveoli. The oxygen enters into the bloodstream. Is switched with the carbon dioxide in the bloodstream. The carbon dioxide enters through the alveoli. Through the narrow bronchioles. Into the lungs. The carbon dioxide is exhaled out of the body.

Q: Solar panels actually comprise many, smaller units called photovoltaic cells. Photovoltaic simply means they convert sunlight into electricity.). Many cells linked together make up a solar panel. Each photovoltaic cell is basically a sandwich made up of two slices of semi-conducting material, usually silicon : . Manufacturers "dope" silicon with other materials, giving each slice of the sandwich a positive or negative electrical charge. This adds extra electrons, with a negative charge, to that layer. Meanwhile, the bottom layer gets a dose of boron, which results in fewer electrons, or a positive charge. This all adds up to an electric field at the junction between the silicon layers. When a photon of sunlight knocks an electron free, the electric field will push that electron out of the silicon junction. A couple of other components of the cell turn these electrons into usable power.

A:
How does a solar panel work?
