Ex Input:
In 1863, Alexander II re-convened the Diet of Finland and initiated several reforms increasing Finland's autonomy from Russia including establishment of its own currency, the markka. Liberation of business led to increased foreign investment and industrial development. Finland also got its first railways, separately established under Finnish administration. Finally, the elevation of Finnish from a language of the common people to a national language equal to Swedish opened opportunities for a larger proportion of the society. Alexander II is still regarded as "The Good Tsar" in Finland. These reforms could be seen as results of a genuine belief that reforms were easier to test in an underpopulated, homogeneous country, than in the whole of Russia. They may also be seen as a reward for the loyalty of its relatively western-oriented population during the Crimean War and during the Polish uprising. Encouraging Finnish nationalism and language can also be seen as an attempt to dilute ties with Sweden. <sep>How could Alexander II's reform be viewed?<sep>Friends

Ex Output:
No


Ex Input:
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>What does the standard definition of gravity indicate?<sep>Anything that has mass exerts a force of gravity and can exert that force on other objects

Ex Output:
Yes

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>What two things happen to a plants' leaves as winter approaches?<sep>They may change color and fall off

Ex Output:

Yes
