Question: Answer the following question given this paragraph: molecular masses. Primary amines tend to have boiling points intermediate between those of the corresponding alcohol and alkane. Moreover, secondary and tertiary amines have lower boiling points than primary amines of comparable molecular mass. Tertiary amines form cations analogous to the ammonium ion (NH 4+), in which all four H atoms are replaced by alkyl groups. Such substances, calledquaternary ammonium salts, can be chiral if all four substituents are different. (Amines with three different substituents are also chiral because the lone pair of electrons represents a fourth substituent. ) Alkylamines can be prepared by nucleophilic substitution reactions of alkyl halides with ammonia or other amines: Equation 24.12. Q: Which reaction between alkyl halides and ammonia makes alkylamines? A:
OPTIONS:
- nitrogen catabolism
- conductive substitution reactions
- nucleophobic reactions
- nucleophilic substitution reactions
Answer: nucleophilic substitution reactions

input with options: Answer the following question given this paragraph: The respiratory system is the body system that exchanges gases with the outside air. It brings air containing oxygen into the body for the cells. It also releases carbon dioxide from the cells into the air. This exchange of gases is called respiration. Q: Which system in the body exchanges gases with the outside air? A:
OPTIONS:
- immune
- digestive
- vascular
- respiratory
output: respiratory

Q: Answer the following question given this paragraph: Sponges come in a variety of shapes and sizes. For example, they may be shaped like tubes, fans, cones, or just blobs. They range in diameter from about a centimeter (0.4 inches) to over a meter (3.3 feet). Many species live in colonies that may be quite large. Adult sponges are sessile. This means they are unable to move from place to place. Root-like projections anchor them to solid surfaces such as rocks and reefs. Q: Root-like projections anchor adults of what colony-dwelling animals to solid surfaces such as rocks and reefs? A:

OPTIONS:
- anemones
- corals
- molluscs
- sponges

A: sponges

input: OPTIONS:
- earthquake chain
- volcanic system
- volcanic setting
- volcanic chain Now, answer this question: Answer the following question given this paragraph: As the tectonic plates move above a hot spot, they form a chain of volcanoes. The islands of Hawaii formed over a hot spot in the middle of the Pacific plate. The Hawaii hot spot has been active for tens of millions of years. The volcanoes of the Hawaiian Islands formed at this hot spot. Older volcanoes that formed at the hot spot have eroded below sea level. These are called the Emperor Seamounts. Q: What forms when tectonic plates move above a hot spot? A:
A:
output: volcanic chain

Answer the following question given this paragraph: The plot that we know of as a graph was the brainchild of the French mathematician-philosopher Rene Descartes (1596-1650). His studies in mathematics led him to develop what was known as "Cartesian geometry", including the idea of our current graphs. The coordinates are often referred to as Cartesian coordinates. Q: What do we call the mathematical field of study credited to french mathematician-philosopher rene descartes? A:

OPTIONS:
- algebra
- Euclidean geometry
- calculus
- cartesian geometry

Answer: cartesian geometry

Q: Answer the following question given this paragraph: Plants and animals exist in a cycle; each requires products of the other. The thousands of coordinated chemical reactions that keep cells alive are referred to collectively as metabolism. In general, metabolic reactions are divided into two classes: the breaking down of molecules to obtain energy is catabolism, and the building of new molecules needed by living systems is anabolism. Q: What is the term for the metabolic reaction where living systems build new molecules? A:

OPTIONS:
- symbolism
- connectionism
- metabolism
- anabolism

A:
anabolism
