Question:
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? After reading the above, is "Hydrogen" the correct answer to the question "What atoms is water composed of?"? OPTIONS:
- no
- yes

Answer:
yes

Input: Alexander's body was laid in a gold anthropoid sarcophagus that was filled with honey, which was in turn placed in a gold casket. According to Aelian, a seer called Aristander foretold that the land where Alexander was laid to rest "would be happy and unvanquishable forever". Perhaps more likely, the successors may have seen possession of the body as a symbol of legitimacy, since burying the prior king was a royal prerogative. While Alexander's funeral cortege was on its way to Macedon, Ptolemy seized it and took it temporarily to Memphis. His successor, Ptolemy II Philadelphus, transferred the sarcophagus to Alexandria, where it remained until at least late Antiquity. Ptolemy IX Lathyros, one of Ptolemy's final successors, replaced Alexander's sarcophagus with a glass one so he could convert the original to coinage. The recent discovery of an enormous tomb in northern Greece, at Amphipolis, dating from the time of Alexander the Great has given rise to speculation that its original intent was to be the burial place of Alexander. This would fit with the intended destination of Alexander's funeral cortege. Pompey, Julius Caesar and Augustus all visited the tomb in Alexandria, where Augustus, allegedly, accidentally knocked the nose off. Caligula was said to have taken Alexander's breastplate from the tomb for his own use. Around AD 200, Emperor Septimius Severus closed Alexander's tomb to the public. His son and successor, Caracalla, a great admirer, visited the tomb during his own reign. After this, details on the fate of the tomb are hazy. The so-called "Alexander Sarcophagus", discovered near Sidon and now in the Istanbul Archaeology Museum, is so named not because it was thought to have contained Alexander's remains, but because its bas-reliefs depict Alexander and his companions fighting the Persians and hunting. It was originally thought to have been the sarcophagus of Abdalonymus (died 311 BC), the king of Sidon appointed by Alexander immediately following the battle of Issus in 331. However, more recently, it has been suggested that it may date from earlier than Abdalonymus' death.

Input: Heat supplies the energy that causes motion. The deeper you go into toward the Earths core, the hotter it gets. At the core it is really hot. All that heat tries to rise toward the surface. In the Mantle, the rock is partially melted and is able to move. As it is heated, the material in the mantle moves toward the surface. As the mantle material rises, it cools. When it reaches the Earths crust, it is mostly stopped. A little of the material can break through the surface, but not all. Instead, it begins to move horizontally. The mantle material moves horizontally away from a mid-ocean ridge crest. Toward the surface, the mantle material starts to cool. As it cools it sinks back down into the mantle. These areas are where deep sea trench occur. The material sinks back down to the core. The system operates like a giant conveyor belt. The motion due to heating and cooling is called convection.

Does the response "Because the motion between heating and cooling" correctly answer the question "Why does the system work as a conveyor belt?"?

OPTIONS:
- no
- yes

The Venetian artist Jacopo de' Barbari, whom Durer had met in Venice, visited Nuremberg in 1500, and Durer said that he learned much about the new developments in perspective, anatomy, and proportion from him. De' Barbari was unwilling to explain everything he knew, so Durer began his own studies, which would become a lifelong preoccupation. A series of extant drawings show Durer's experiments in human proportion, leading to the famous engraving of Adam and Eve (1504), which shows his subtlety while using the burin in the texturing of flesh surfaces. This is the only existing engraving signed with his full name. Durer made large numbers of preparatory drawings, especially for his paintings and engravings, and many survive, most famously the Betende Hande (English: Praying Hands, c. 1508 Albertina, Vienna), a study for an apostle in the Heller altarpiece. He also continued to make images in watercolour and bodycolour (usually combined), including a number of still lifes of meadow sections or animals, including his Young Hare (1502) and the Great Piece of Turf (1503, both also Albertina).

Question: "What sort of subjects were in Durer's artworks?"

OPTIONS:
- no
- yes

Answer: "Watercolour and bodycolour"

Response: no

Question:
Late on the next Sunday afternoon Gifford had gone for a country walk which he had arranged to bring him round in time for the evening service at the little village church of Wynford standing just outside the park boundary. His way took him by well-remembered field-paths which, although towards the end of his walk darkness had set in, he had no difficulty in tracing. The last field he crossed brought him to a by-road joining the highway which ran through Wynford, the junction being about a quarter of a mile from the church. As he neared the stile which admitted to the road he saw, on the other side of the hedge and showing just above it, the head of a man. At the sound of his footsteps the man quickly turned, and, as for a moment the fitful moonlight caught his face, Gifford was sure he recognized Gervase Henshaw. But he took no notice and kept on his way to the stile, which he crossed and gained the road. As he did so he glanced back. A horse and trap was waiting there with Henshaw in it. He was now bending down, probably with the object of concealing his identity, and had moved on a few paces farther down the road. After reading the above, is "Late next Sunday afternoon" the correct answer to the question "When did Gifford take the well-remembered fields path?"? OPTIONS:
- no
- yes

Answer:
yes
