Example Input: A day at the beach. When Sam woke in the morning, he was super excited! Today was the day! It was Sunday, the day that Sam's mom and dad had promised to take Sam to the beach. Sam's grandma had given a pail and shovel to Sam to use in the sand. At breakfast Sam was so excited he was wiggling in his seat! Mom told Sam that they would leave when the big hand on the clock was pointing to the 10, and the little had was pointing to the 12. Mom asked Sam if he would like to help make sandwiches for the trip, and Sam said that he wanted to help. Dad said, "let's make a game of it, we need to make a sandwich for each of us. There are three of us, so we need three sandwiches. Let's count as we make the sandwiches!" Sam counted as mom made the sandwiches, one for dad, one for mom and one for Sam. Then mom started to make another sandwich! "Mom!" said Sam, "we have three sandwiches and that makes one sandwich for each of us." Sam's mom laughed, "You're right Sam!" Sam's mom said she was being silly. <sep>What was Sam's game with the sandwiches?<sep>Counting
Example Output: Yes

Example Input: Plants also detect the daily cycle of light and darkness. Do you know how plants respond to these changes? Some plants open their leaves during the day. It is during these hours the plant can collect sunlight. At night, the plant closes its leaves to prevent water loss. Many plants respond to the change in the length of the day. As days grow shorter, some plants respond by going dormant. Dormant is when a plant suspends its growth. It does this in order to survive. Shorter days signal the coming of winter. Winter in most areas means extreme cold. It is also very dry in the winter months. As winter approaches, some plants respond by their leaves changing color. After the change in color, they fall off. This dormancy period helps trees. It allows them to survive the cold and dry winter. Plants only want to grow when conditions are right. <sep>Do some plants' leaves fall off in the winter months?<sep>No, they fall off in the autumn only
Example Output: No

Example Input: The properties of matter depend on the types of atoms that matter is made of. Matter can exist in two forms. It can be a pure substance. This means it is not mixed with anything. It can also be a combination of different substances. This means it can be a mix of different types of atoms. You may recall that atoms differ based on the numbers of protons they contain. Some atoms contain only one proton such as Hydrogen. Other atoms contain many protons. There are many types of atoms. For example, Helium has two protons. An Oxygen atom has eight. Water is composed of a two types of atoms. Water is made of two Hydrogen atoms and one Oxygen atoms. There are only so many types of atoms. These atoms can be mixed into an almost limitless amount of substances. So what do we call a substance that has only a single type of atom? <sep>Water is composed of which two atoms?<sep>Helium and hydrogen
Example Output:
No
