Q: Answer the following question given this paragraph: Differences in density between water and air lead to differences in pressure. Q: Differences in density between water and air lead to differences in what? A:

OPTIONS:
- resistance

A: pressure

input: OPTIONS:
- covalent bonds
- soluble bonds
- magnetic bonds
- ionic bonds Now, answer this question: Answer the following question given this paragraph: polar, while others are strongly polar. Ionic bonds can be considered the ultimate in polarity, with electrons being transferred rather than shared. To judge the relative polarity of a covalent bond, chemists use electronegativity, which is a relative measure of how strongly an atom attracts electrons when it forms a covalent bond. There are various numerical scales for rating electronegativity. Figure 4.4 "Electronegativities of Various Elements" shows one of the most popularthe Pauling scale. The polarity of a covalent bond can be judged by determining the difference in the electronegativities of the two atoms making the bond. The greater the difference in electronegativities, the greater the imbalance of electron sharing in the bond. Although there are no hard and fast rules, the general rule is if the difference in electronegativities is less than about 0.4, the bond is considered nonpolar; if the difference is greater than 0.4, the bond is considered polar. If the difference in electronegativities is large enough (generally greater than about 1.8), the resulting compound is considered ionic rather than covalent. An electronegativity difference of zero, of course, indicates a nonpolar covalent bond. Q: What kind of bonds, where electrons are transferred rather than shared, are considered the ultimate in polarity? A:
A:
output: ionic bonds

Answer the following question given this paragraph: Flaps of tissue called valves separate the heart's chambers. Valves keep blood flowing in just one direction through the heart. For example, a valve at the bottom of the right atrium opens to let blood flow from the right atrium to the right ventricle. Then the valve closes so the blood can't flow back into the right atrium. Q: What is the largest artery in the body called? A:

OPTIONS:
- ventricular
- carotid
- radial
- aorta

Answer: aorta

Problem: OPTIONS:
- succinct
- inherited
- occuring
- extinct
Q: Answer the following question given this paragraph: Most of the organisms that once lived on Earth are now extinct. Earth's environment has changed many times. Many organisms could not adapt to the changes. They died out. The organisms that did survive passed traits on to their offspring. The changes added up, eventually producing the species we see today. Q: Species of organisms that have permanently died out can also be called what? A:
Answer: extinct

OPTIONS:
- the pupil
- the vitreous fluid
- the cornea
- the retina

Answer:
the retina
