Based on the information present in the given passage, you need to write a correct answer to the given question. A correct answer is one that correctly and completely answers the question. Do not write answers that address the question partially or incorrectly. The correct answer must be contained in the given paragraph.

[EX Q]: Paragraph- Sent 1: Conduction is the transfer of thermal energy.
Sent 2: It occurs between objects or substances that are touching.
Sent 3: Thermal conductors are materials that are good conductors of heat.
Sent 4: Thermal insulators are materials that are poor conductors of heat.
Sent 5: Both conductors and insulators have important uses.
Sent 6: Convection is the transfer of thermal energy.
Sent 7: This occurs as particles move within a fluid.
Sent 8: The fluid may be a liquid or a gas.
Sent 9: The particles within the fluid transfer energy by moving from warmer to cooler areas.
Sent 10: They move in loops.
Sent 11: These loops are called convection currents.
Sent 12: Radiation is the transfer of thermal energy by waves.
Sent 13: These waves can travel through empty space.
Sent 14: When the waves reach objects, the heat is transferred to the objects.
Sent 15: Radiation is how the Sun warms the Earths surface. 
Question: What is an example of radiant heat?.
[EX A]: The sun.

[EX Q]: Paragraph- Sent 1: You couldnt survive without your skin.
Sent 2: It has many important functions.
Sent 3: The main function of the skin is controlling what enters and leaves the body.
Sent 4: It prevents the loss of too much water from the body.
Sent 5: It also prevents bacteria and other microorganisms from entering the body.
Sent 6: The skin helps maintain a constant body temperature.
Sent 7: It keeps the body cool in two ways.
Sent 8: Sweat from sweat glands in the skin evaporates to cool the body.
Sent 9: Blood vessels in the skin dilate, or widen.
Sent 10: This action increases blood flow to the body surface.
Sent 11: This allows more heat to reach the surface.
Sent 12: The heat is then able to radiate off the body.
Sent 13: The opposite happens to retain body heat.
Sent 14: Blood vessels in the skin constrict, or narrow.
Sent 15: This decreases blood flow to the body surface.
Sent 16: This reduces the amount of heat that reaches the surface.
Sent 17: When this happens, less heat can be lost to the air. 
Question: What is different when something constricts as compared to when it dilates?.
[EX A]: Diameter.

[EX Q]: Paragraph- Sent 1: Not until 1998 did al Qaeda undertake a major terrorist operation of its own, in large part because  Bin Laden lost his base in Sudan.
Sent 2: Ever since the Islamist regime came to power in Khartoum, the United States and other Western governments had pressed it to stop providing a haven for terrorist organizations.
Sent 3: Other governments in the region, such as those of Egypt, Syria, Jordan, and even Libya, which were targets of some of these groups, added their own pressure.
Sent 4: At the same time, the Sudanese regime began to change.
Sent 5: Though Turabi had been its inspirational leader, General Omar al Bashir, president since 1989, had never been entirely under his thumb.
Sent 6: Thus as outside pressures mounted, Bashir's supporters began to displace those of Turabi.
Sent 7: The attempted assassination in Ethiopia of Egyptian President Hosni Mubarak in June 1995 appears to have been a tipping point.
Sent 8: The would-be killers, who came from the Egyptian Islamic Group, had been sheltered in Sudan and helped by  Bin Laden.
Sent 9: When the Sudanese refused to hand over three individuals identified as involved in the assassination plot, the UN Security Council passed a resolution criticizing their inaction and eventually sanctioned Khartoum in April 1996.
Sent 10: A clear signal to  Bin Laden that his days in Sudan were numbered came when the government advised him that it intended to yield to Libya's demands to stop giving sanctuary to its enemies.
Sent 11:  Bin Laden had to tell the Libyans who had been part of his Islamic army that he could no longer protect them and that they had to leave the country.
Sent 12: Outraged, several Libyan members of al Qaeda and the Islamic Army Shura renounced all connections with him.
Sent 13:  Bin Laden also began to have serious money problems.
Sent 14: International pressure on Sudan, together with strains in the world economy, hurt Sudan's currency.
Sent 15: Some of  Bin Laden's companies ran short of funds.
Sent 16: As Sudanese authorities became less obliging, normal costs of doing business increased.
Sent 17: Saudi pressures on the  Bin Laden family also probably took some toll.
Sent 18: In any case,  Bin Laden found it necessary both to cut back his spending and to control his outlays more closely. 
Question: What are three reasons for  Bin Laden's money troubles when he was based in Sudan?.
[EX A]:
International pressure on Sudan that affected its currency, less obliging authorities and Saudi pressure.
