Problem: 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.

Question: "Why do plants close their leaves at night?"

Answer: "Because the sun isn't out"
Answer: no

Problem: Albanian was proved to be an Indo-European language in 1854 by the German philologist Franz Bopp. The Albanian language comprises its own branch of the Indo-European language family. Some scholars believe that Albanian derives from Illyrian while others claim that it derives from Daco-Thracian. (Illyrian and Daco-Thracian, however, might have been closely related languages; see Thraco-Illyrian.) Establishing longer relations, Albanian is often compared to Balto-Slavic on the one hand and Germanic on the other, both of which share a number of isoglosses with Albanian. Moreover, Albanian has undergone a vowel shift in which stressed, long o has fallen to a, much like in the former and opposite the latter. Likewise, Albanian has taken the old relative jos and innovatively used it exclusively to qualify adjectives, much in the way Balto-Slavic has used this word to provide the definite ending of adjectives. The cultural renaissance was first of all expressed through the development of the Albanian language in the area of church texts and publications, mainly of the Catholic region in the North, but also of the Orthodox in the South. The Protestant reforms invigorated hopes for the development of the local language and literary tradition when cleric Gjon Buzuku brought into the Albanian language the Catholic liturgy, trying to do for the Albanian language what Luther did for German.

Question: "What are some reasons for uses of the Albanian language?"

Answer: "Church publications"
Answer: yes

Problem: Rolfe put down the little dog he had been holding, and went out into the hall. The dog accompanied him, frisking about him in friendly fashion. Rolfe first examined the bedroom that he had seen Inspector Chippenfield enter. It was a small room, containing a double bed. It was prettily furnished in white, with white curtains, and toilet-table articles in ivory to match. A glance round the room convinced Rolfe that it was impossible for a man to secrete himself in it. The door of the wardrobe had been flung open by the inspector, and the dresses and other articles of feminine apparel it contained flung out on the floor. There was no other hiding-place possible, except beneath the bed, and the ruthless hand of the inspector had torn off the white muslin bed hangings, revealing emptiness underneath. Rolfe went out into the hall again, and entered the room next the bedroom. This apartment was apparently used as a dining-room, for it contained a large table, a few chairs, a small sideboard, a spirit-stand, a case of books and ornaments, and two small oak presses. Plainly, there was no place in it where a man could hide himself. The next room was the bathroom, which was also empty. Opposite the bathroom was a small bedroom, very barely furnished, offering no possibility of concealment. Then the passage opened into a large roomy kitchen, the full width of the rooms on both sides of the hall, and the kitchen completed the flat.

Question: "In what room did Rolfe find a double bed?"

Answer: "The bedroom"
Answer:
yes
