Answer the following question given this paragraph: Convergent plate boundaries also produce strong, deadly earthquakes. Earthquakes mark the motions of colliding plates and the locations where plates plunge into the mantle. These earthquakes can be shallow, intermediate or deep focus. Q: Earthquakes mark the motions of colliding plates and the locations where plates plunge into what? A:
OPTIONS:
- the mesosphere
- the crust
- the core
- the mantle
the mantle

Answer the following question given this paragraph: Coal is the source of most electricity. Q: What is the source of most electricity? A:
OPTIONS:
- methane
- the Sun
- air
- coal

Answer: coal

Question: Answer the following question given this paragraph: These include anterior-posterior movements of the arm at the shoulder, the forearm at the elbow, the hand at the wrist, and the fingers at the metacarpophalangeal and interphalangeal joints. For the thumb, extension moves the thumb away from the palm of the hand, within the same plane as the palm, while flexion brings the thumb back against the index finger or into the palm. These motions take place at the first carpometacarpal joint. In the lower limb, bringing the thigh forward and upward is flexion at the hip joint, while any posterior-going motion of the thigh is extension. Note that extension of the thigh beyond the anatomical (standing) position is greatly limited by the ligaments that support the hip joint. Knee flexion is the bending of the knee to bring the foot toward the posterior thigh, and extension is the straightening of the knee. Flexion and extension movements are seen at the hinge, condyloid, saddle, and ball-and-socket joints of the limbs (see Figure 9.12a-d). Hyperextension is the abnormal or excessive extension of a joint beyond its normal range of motion, thus resulting in injury. Similarly, hyperflexion is excessive flexion at a joint. Hyperextension injuries are common at hinge joints such as the knee or elbow. In cases of "whiplash" in which the head is suddenly moved backward and then forward, a patient may experience both hyperextension and hyperflexion of the cervical region. Q: What term means the abnormal or excessive extension of a joint - particularly a hinged joint - beyond its normal range of motion, thus resulting in injury? A:
OPTIONS:
- sprain
- tear
- hypercorrection
- hyperextension
Answer: hyperextension

input with options: Answer the following question given this paragraph: Covalent bonds form because they give atoms a more stable arrangement of electrons. Look at the hydrogen atoms in Figure above . Alone, each hydrogen atom has just one electron. By sharing electrons with another hydrogen atom, it has two electrons: its own and the one in the other hydrogen atom. The shared electrons are attracted to both hydrogen nuclei. This force of attraction holds the two atoms together as a molecule of hydrogen. Q: What bonds form because they give atoms a more stable arrangement of electrons? A:
OPTIONS:
- Hydrogen bond
- Ionic bond
- Polar bond
- covalent
output: covalent

Q: Answer the following question given this paragraph: This bottle of water models the semicircular canals in your ears. When you tip the bottle, the water moves up or down the sides of the bottle; when you tip your head, the liquid inside the semicircular canals moves up and down the sides of the canals. Tiny hair cells lining the canals sense the movement of liquid and send messages to the brain. Q: What senses the movement of liquid in ear canals? A:

OPTIONS:
- Ear Drum
- Brain Cells
- muscle cells
- hair cells

A: hair cells

Answer the following question given this paragraph: Anions form when an atom gains electrons. Nonmetallic atoms typically gain enough electrons to obtain the same electron configuration as the nearest noble gas. All the elements in Group 17 have seven valence electrons, which are arranged into an outer configuration of n s 2 n p 5 . To achieve a noble gas configuration ( n s 2 n p 6 ), each of these elements needs to gain just one electron, resulting in an anion with a 1 charge. Similarly, Group 16 elements can obtain an n s 2 n p 6 valence configuration by forming ions with a 2 charge, and the Group 15 nonmetals will form ions with a 3 charge. Naming anions is slightly different than naming cations. The end of the element's name is dropped and replaced with the ide suffix. For example, when the chlorine atom (Cl) gains one electron, it becomes the chloride ion (Cl - ). This structure has the same electron configuration as the noble gas argon. Similarly, sulfur can gain two electrons to become the sulfide ion (S 2- ), which also has a noble gas configuration. Q: What forms when an atom gains electrons? A:
OPTIONS:
- cations
- bonds
- crystals
- anions
anions
