Answer the following question given this paragraph: Most scientists who study dark matter think it is a combination. Ordinary matter is part of it. That is mixed with some kind of matter that we haven't discovered yet. Most scientists think that ordinary matter is less than half of the total matter in the Universe. Q: Most scientists think that ordinary matter makes up how much of the total matter in the universe? A:

OPTIONS:
- greater than half
- about half
- more than half
- less than half

Answer: less than half

Problem: OPTIONS:
- proteins
- molecule
- atom
- cell
Q: Answer the following question given this paragraph: A cell is the smallest independently functioning unit of a living organism. Even bacteria, which are extremely small, independently-living organisms, have a cellular structure. Each bacterium is a single cell. All living structures of human anatomy contain cells, and almost all functions of human physiology are performed in cells or are initiated by cells. A human cell typically consists of flexible membranes that enclose cytoplasm, a water-based cellular fluid together with a variety of tiny functioning units called organelles. In humans, as in all organisms, cells perform all functions of life. A tissue is a group of many similar cells (though sometimes composed of a few related types) that work together to perform a specific function. An organ is an anatomically distinct structure of the body composed of two or more tissue types. Each organ performs one or more specific physiological functions. An organ system is a group of organs that work together to perform major functions or meet physiological needs of the body. This book covers eleven distinct organ systems in the human body (Figure 1.4 and Figure 1.5). Assigning organs to organ systems can be imprecise since organs that "belong" to one system can also have functions integral to another system. In fact, most organs contribute to more than one system. Q: What is the smallest independently functioning unit of a living organism? A:
Answer: cell

Problem:OPTIONS:
- alkaloids
- oxides
- carborane
- carbides

Answer the following question given this paragraph: Note the Pattern Pi bonds between carbon and the heavier chalcogenides are weak due to poor orbital overlap. Binary compounds of carbon with less electronegative elements are called carbides. The chemical and physical properties of carbides depend strongly on the identity of the second element, resulting in three general classes: ionic carbides, interstitial carbides, and covalent carbides. The reaction of carbon at high. Q: Binary compounds of carbon with less electronegative elements are called what? A:
****
A: carbides

Answer the following question given this paragraph: Animal behavior is any way that an animal interact with other animals or the environment. An animal may carry out behaviors alone or with other animals. The photos in Figure below show just a few of the ways that animals behave. Look at the pictures and read about the behaviors they represent. Why do you think the animals are behaving in these ways? And how do the behaviors come about? Which, if any of them, have to be learned?. Q: What is the term for any way that an animal interacts with other animals or the environment? A:
OPTIONS:
- animal biology
- animal way
- immunity
- animal behavior
animal behavior

Answer the following question given this paragraph: Examples of machines that increase the distance over which force is applied are paddles and hammers. Figure below explains how these machines work. In each case, the machine increases the distance over which the force is applied, but it reduces the strength of the applied force. Q: Paddles and hammers are examples of simple machines that increase the distance over which force is applied, while reducing what? A:
OPTIONS:
- momentum
- gravity
- intensity
- strength

Answer: strength

input with options: Answer the following question given this paragraph: Most air masses form over polar or tropical regions. They may form over continents or oceans. Air masses are moist if they form over oceans. They are dry if they form over continents. Air masses that form over oceans are called maritime air masses. Those that form over continents are called continental air masses. Figure below shows air masses that form over or near North America. Q: Most air masses form over what two types of regions? A:
OPTIONS:
- arctic and marine
- polar and arctic
- marine and tropical
- polar and tropical
output:
polar and tropical
