So what is gravity? A typical definition of gravity is that it is a force. It causes an attraction between two masses. According to this definition, anything that has mass exerts a force. Any object exerts gravity on other objects. It does not matter how small it is, it has gravity. The more matter an object has, the more gravity it has. Your pencil has a tiny bit of gravity, but far too little to notice. What about a planet? It would have a lot of gravity. An objects gravity exerts a pull on other objects. Friction only occurs between objects that are touching. Gravity can act between objects that are not touching. In fact, gravity can act over very long distances. Where else can you feel gravity? <sep>How do objects interact under gravity?<sep>gravity causes an attraction between two masses

Ex Output:
Yes


Ex Input:
Johnnie had a set of small volumes of English verse, extensively annotated by his own hand, which Stoddard had brought to her early in their acquaintance, leaving it with her more as a gift than as a loan.  She kept these little books after all the others had gone back.  She had read and reread them--cullings from Chaucer, from Spenser, from the Elizabethan lyrists, the border balladry, fierce, tender, oh, so human--till she knew pages of them by heart, and their vocabulary influenced her own, their imagery tinged all her leisure thoughts.  It seemed to her, whenever she debated returning them, that she could not bear it.  She would get them out and sit with one of them open in her hands, not reading, but staring at the pages with unseeing eyes, passing her fingers over it, as one strokes a beloved hand, or turning through each book only to find the pencilled words in the margins.  She would be giving up part of herself when she took these back.  Yet it had to be done, and one miserable morning she made them all into a neat package, intending to carry them to the mill and place them on Stoddard's desk thus early, when nobody would be in the office.  Then the children came in; Deanie was half sick; and in the distress of getting the ailing child comfortably into her own bed, Johnnie forgot the books.  Taking them in at noon, she met Stoddard himself. <sep>In what books were the words from Chaucer and Spenser?<sep>Small volumes of English verse

Ex Output:
Yes


Ex Input:
An insect can have one of three types of change in its life. A metamorphosis describes how insects change. Some insects do not go through a change. Instead, the young look like small versions of adults. The only change between young and mature is size. Other types of insects go through a change in physical appearance. There are two types of this type of change. Some insects change only slightly during their change. This type is called incomplete metamorphosis. Other types of insects go through a major change. They don't look at all like the adult when they are born. This type of change is called complete metamorphosis. Occurs in the most primitive insects. Newborn insect looks like a tiny version of the adult. Incomplete Three stages: egg, nymph, and adult. Young, called nymphs, usually similar to adult. Growth occurs during the nymph stage. <sep>What do the young of insects who do not go through a change look like?<sep>Like a different animal
