Question:
Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video. After reading the above, is "The conductivity of an object" the correct answer to the question "What is density?"?

Answer:
no

Question:
The Reconquest: The aim of the Crusades in Spain was the eviction of the Muslims. After the recovery of Jerusalem in 1099, it took four hundred years of sieges and battles, treaties, betrayals, and yet more battles, before Christian kings and warlords succeeded in subduing the Moors. On 10 September 1229, a Catalan army led by King Jaume I of Aragon and Catalunya took the Mallorcan shore near the present-day resort of Santa Ponca. The defenders retreated inside the walls of Palma, but on the last day of 1229 the city fell, and pockets of resistance throughout the island were also defeated. Jaume I proved to be an enlightened ruler who profited from the talents of the Moorsconverted by force to Christianityas well as of the island's large Jewish and Genoese trading communities. Mallorca prospered. The Moors on Menorca speedily agreed to pay an annual tribute to Aragon and were left in peace. The island's tranquility lasted until 1287, when Alfonso III of Aragon, smarting over a series of humiliations at the hands of his nobles, found a pretext for invasion. The Moors were defeated and expelled or killed. In contrast to Mallorca, Menorca's economy was devastated for decades. Jaume I died after reigning in Aragon for six decades, but he made the cardinal error of dividing between his sons the lands he had fought for so long to unite. At first this resulted in an Independent Kingdom of Mallorca, under Jaume II, followed by Sanc and Jaume III. But family rivalry triggered the overthrow of Jaume III by his cousin Pedro IV, who then seized the Balearics for Aragon. Attempting a comeback, Jaume was killed in battle near Llucmajor in 1349. A newly unified Christian Spain under the Catholic Monarchs, Ferdinand and Isabella, completed the Reconquest, defeating the only Moorish enclave left on the Iberian peninsula, Granada, in 1492. However, the centralized kingdom failed to incorporate the Balearics politically or economically. After reading the above, is "Paid a tribute to be left alone" the correct answer to the question "What three things did we learn about the Moors?"?

Answer:
yes

Question:
As Philip marched south, his opponents blocked him near Chaeronea, Boeotia. During the ensuing Battle of Chaeronea, Philip commanded the right wing and Alexander the left, accompanied by a group of Philip's trusted generals. According to the ancient sources, the two sides fought bitterly for some time. Philip deliberately commanded his troops to retreat, counting on the untested Athenian hoplites to follow, thus breaking their line. Alexander was the first to break the Theban lines, followed by Philip's generals. Having damaged the enemy's cohesion, Philip ordered his troops to press forward and quickly routed them. With the Athenians lost, the Thebans were surrounded. Left to fight alone, they were defeated. After the victory at Chaeronea, Philip and Alexander marched unopposed into the Peloponnese, welcomed by all cities; however, when they reached Sparta, they were refused, but did not resort to war. At Corinth, Philip established a "Hellenic Alliance" (modeled on the old anti-Persian alliance of the Greco-Persian Wars), which included most Greek city-states except Sparta. Philip was then named Hegemon (often translated as "Supreme Commander") of this league (known by modern scholars as the League of Corinth), and announced his plans to attack the Persian Empire. After reading the above, is "The Hellenic Alliance" the correct answer to the question "What were the two groups that Philip and Alexander fought against?"?

Answer:
no
