input with options: Answer the following question given this paragraph: Testes The testes (singular = testis) are the male gonadsthat is, the male reproductive organs. They produce both sperm and androgens, such as testosterone, and are active throughout the reproductive lifespan of the male. Paired ovals, the testes are each approximately 4 to 5 cm in length and are housed within the scrotum (see Figure 27.3). They are surrounded by two distinct layers of protective connective tissue (Figure 27.4). The outer tunica vaginalis is a serous membrane that has both a parietal and a thin visceral layer. Beneath the tunica vaginalis is the tunica albuginea, a tough, white, dense connective tissue layer covering the testis itself. Not only does the tunica albuginea cover the outside of the testis, it also invaginates to form septa that divide the testis into 300 to 400 structures called lobules. Within the lobules, sperm develop in structures called seminiferous tubules. During the seventh month of the developmental period of a male fetus, each testis moves through the abdominal musculature to descend into the scrotal cavity. This is called the "descent of the testis. " Cryptorchidism is the clinical term used when one or both of the testes fail to descend into the scrotum prior to birth. Q: What is the name for the male reproductive organs or gonads? A:
OPTIONS:
- nucleus
- anus
- ovaries
- testes
output: testes

Q: Answer the following question given this paragraph: Another benefit of Earth's magnetic field is its use for navigation. People use compasses to detect Earth's magnetic north pole and tell direction. Many animals have natural "compasses" that work just as well. For example, the loggerhead turtle in the Figure below senses the direction and strength of Earth's magnetic field and uses it to navigate along migration routes. Many migratory bird species can also sense the magnetic field and use it for navigation. Recent research suggests that they may have structures in their eyes that let them see Earth's magnetic field as a visual pattern. You can learn more at this URL: http://www. smithsonianmag. com/science-nature/How-Do-Birds-Find-Their-Way-Home. html. Q: What part of earth do many animals use for navigation? A:

OPTIONS:
- oceans
- atmosphere
- molten core
- magnetic field

A: magnetic field

input: OPTIONS:
- pyroclastic winds
- planetary winds
- prevailing winds
- katabatic winds Now, answer this question: Answer the following question given this paragraph: Katabatic winds move the same way as mountain and valley breezes. However, they are much stronger. Katabatic winds form over a high plateau that is surrounded by mountains. In winter, the plateau grows cold. Air sinks through the gaps in the mountains. Over Antarctica and Greenland, these winds are frigid. Q: What type of winds move the same way as mountain and valley breezes? A:
A:
output: katabatic winds

Answer the following question given this paragraph: A solution is another name for a homogeneous mixture. http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gob-ch01defined a mixture as a material composed of two or more substances. In a solution, the combination is so intimate that the different substances cannot be differentiated by sight, even with a microscope. Compare, for example, a mixture of salt and pepper and another mixture consisting of salt and water. In the first mixture, we can readily see individual grains of salt and the flecks of pepper. A mixture of salt and pepper is not a solution. However, in the second mixture, no matter how carefully we look, we cannot see two different substances. Salt dissolved in water is a solution.

OPTIONS:
- structure
- mixture
- element
- solution

Answer: solution

Problem: OPTIONS:
- growth
- respiratory
- circulatory
- digestive
Q: Answer the following question given this paragraph: In the digestive system, food is digested and its nutrients are absorbed by the blood for transport around the body. The blood is part of the cardiovascular system. Q: Nutrients from food are absorbed by the blood for transport around the body as part of what system? A:
Answer: digestive

Answer the following question given this paragraph: You can see how Mendeleev organized the elements in Figure below . From left to right across each row, elements are arranged by increasing atomic mass. Mendeleev discovered that if he placed eight elements in each row and then continued on to the next row, the columns of the table would contain elements with similar properties. He called the columns groups . They are sometimes called families, because elements within a group are similar but not identical to one another, like people in a family. Q: In the periodic table, elements are arranged from left to right according to what property? A:

OPTIONS:
- metallic mass
- real mass
- major mass
- atomic mass

Answer:
atomic mass
