Answer the following question given this paragraph: It was not until the era of the ancient Greeks that we have any record of how people tried to explain the chemical changes they observed and used. At that time, natural objects were thought to consist of only four basic elements: earth, air, fire, and water. Then, in the fourth century BC, two Greek philosophers, Democritus and Leucippus, suggested that matter was not infinitely divisible into smaller particles but instead consisted of fundamental, indivisible particles called atoms. Unfortunately, these early philosophers did not have the technology to test their hypothesis. They would have been unlikely to do so in any case because the ancient Greeks did not conduct experiments or use the scientific method. They believed that the nature of the universe could be discovered by rational thought alone. Over the next two millennia, alchemists, who engaged in a form of chemistry and speculative philosophy during the Middle Ages and Renaissance, achieved many advances in chemistry. Their major goal was to convert certain elements into others by a process they called transmutation (Figure 1.13 "An Alchemist at Work"). In particular, alchemists wanted to find a way to transform cheaper metals into gold. Although most alchemists did not approach chemistry systematically and many appear to have been outright frauds, alchemists in China, the Arab kingdoms, and medieval Europe made major contributions, including the discovery of elements such as quicksilver (mercury) and the preparation of several strong acids. Q: It was not until the era of the ancient greeks that we have any record of how people tried to explain the chemical changes they observed and used. at that time, natural objects were thought to consist of only four basic elements: earth, air, fire, and this? A:
OPTIONS:
- sky
- soul

- water

Answer: water

Question: Answer the following question given this paragraph: Figure 4.16 Lactic acid fermentation is common in muscles that have become exhausted by use. Q: What is common in muscles that have become exhausted by use? A:
OPTIONS:
- Blood Acid Fermentation
- vibration acid fermentation
- clumps acid fermentation
- lactic acid fermentation
Answer: lactic acid fermentation

input with options: Answer the following question given this paragraph: A ribosome is a small organelle where proteins are made. It's like a factory in the cell. It gathers amino acids and joins them together into proteins. Unlike other organelles, the ribosome is not surrounded by a membrane. As a result, some scientists do not classify it as an organelle. Ribosomes may be found floating in the cytoplasm. Some ribosomes are located on the surface of another organelle, the endoplasmic reticulum. Q: What is the term for a small organelle where proteins are made? A:
OPTIONS:
- atom
- capsule
- ovary
- ribosome
output: ribosome

Q: Answer the following question given this paragraph: Nearly all earthquakes occur at plate boundaries, and all types of plate boundaries have earthquakes. Q: Nearly all earthquakes occur where? A:

OPTIONS:
- plate centers
- in Asia
- in large cities
- plate boundaries

A: plate boundaries

input: OPTIONS:
- zero sum game
- significant digits
- non-numbers
- left-end zeros Now, answer this question: Answer the following question given this paragraph: 3. Zeros that appear in front of all of the nonzero digits are called left-end zeros. Left-end zeros are never significant. A. 0.008 has one significant figure. Q: Zeros that appear in front of all of the nonzero digits are called what? A:
A:
output: left-end zeros

Question: Answer the following question given this paragraph: Echinoderms are marine organisms that make up the phylum Echinodermata. They can be found in the ocean from the equator to the poles. There are roughly 6000 living species of echinoderms. They are among the most distinctive organisms within the animal kingdom. Members of the phylum include sea stars (starfish), sand dollars, and feather stars, shown in Figure below . See "Different But Equal" at http://www. pbs. org/kcet/shapeoflife/episodes/ultimate. html for an introduction to echinoderms. Q: Echinoderms have what type of body symmetry? A:
OPTIONS:
- Translational symmetry
- Rotational symmetry
- Reflectional symmetry
- radial symmetry
Answer:
radial symmetry
