Correct Answer
A. An African civil warExplanation
Conflict, or Blood, Diamonds are not encouraged to be bought because they fund an African civil war. This means that purchasing these diamonds indirectly supports the violence and conflict happening in African countries. The profits from the sale of these diamonds often go towards funding rebel groups or warlords, who use the money to buy weapons and continue their destructive activities. To prevent the perpetuation of these conflicts, it is important to avoid buying diamonds that are associated with violence and human rights abuses.Rate this question:

Computers for hard drives.
-
Mr. Sampson's coffee mug for heat.
-
Paper for envelopes.
Correct Answer
A. Industry for cutting.Explanation
Diamonds are known for their hardness and durability, making them ideal for industrial applications. They are commonly used in industries for cutting various materials, including metals, stones, and even other diamonds. Due to their exceptional strength, diamonds are able to create precise and clean cuts, making them a valuable tool in industries such as mining, construction, and manufacturing. Therefore, the correct answer is "industry for cutting."Rate this question:

Which of the following is NaCl, or salt?
-
Calcite
-
Halite
-
Talc
-
Quartz
Correct Answer
A. HaliteExplanation
Halite is the correct answer because it is a mineral that is commonly known as rock salt or table salt. It is composed of sodium chloride (NaCl), which is the chemical formula for salt. Calcite, talc, and quartz are different minerals and do not have the same chemical composition as salt.Rate this question:

The Statue of Liberty is made from
-
Pt
-
C
-
Co
-
Cu
-
Fe
Correct Answer
A. CuExplanation

The copper sheets used for the statue were hammered into shape and then assembled on a framework of iron bars. Over time, the copper has oxidized, resulting in the distinctive green patina that we see today. Copper was chosen for its durability and ability to withstand harsh weather conditions, making it an ideal material for such a prominent and enduring symbol.Rate this question:

Eggs and cocoa and oil and water are ingredients for brownies. _________ are the ingredients for rocks.
-
Oysters
-
Minerals
-
Variables
-
Meters

Correct Answer
A. MineralsExplanation
The given correct answer for this question is "minerals". This is because minerals are the ingredients for rocks. Rocks are composed of various minerals, which are naturally occurring inorganic substances that make up the Earth's crust. Therefore, minerals are the essential components that form rocks, similar to how eggs, cocoa, oil, and water are the ingredients for brownies.Rate this question:

In Africa, there are waterfalls and steep cliffs. The terms for these land formations are: (choose both)
-
Cataracts
-
Plateau
-
Plain
-
Escarpments
Correct Answer(s)
A. Cataracts
A. EscarpmentsExplanation
In Africa, cataracts and escarpments are the terms used to describe specific land formations. Cataracts refer to waterfalls, while escarpments are steep cliffs. These terms are used to differentiate between different types of land formations found in Africa. Plateau and plain, on the other hand, do not accurately describe waterfalls or steep cliffs, which is why they are not the correct answers for this question.Rate this question:

A Republic is
-
A monarchy.
-
A dictatorship.
-
A form of government where people choose representatives.
-
Vegetation.
Correct Answer
A. A form of government where people choose representatives.Explanation
A Republic is a form of government where people choose representatives. In a republic, the power to make decisions and govern is held by elected officials who represent the interests of the people. This system allows for the participation of citizens in the decision-making process and ensures that their voices are heard. Unlike a monarchy or dictatorship, where power is concentrated in the hands of a single ruler or a small group, a republic promotes democracy and the idea of government by the people. Vegetation is not related to the concept of a republic.Rate this question:

Igneous rocks form from
-
Cooled magma or lava.
-
Compacted & cemented sediments.
-
Heat and pressure changing existing rocks.
-
The sun's rays hitting the surface.
Correct Answer
A. Cooled magma or lava.Explanation
Igneous rocks form from cooled magma or lava. Magma is molten rock that is found beneath the Earth's surface, while lava is magma that has reached the surface. As magma or lava cools, it solidifies and forms igneous rocks. This process can occur both on land and underwater. The cooling rate of the magma or lava determines the texture of the igneous rock, with slower cooling leading to larger crystals and faster cooling resulting in smaller crystals or even a glassy texture.Rate this question:

A. VariableExplanation
In a lab, the thing that changes is called the variable. A variable is a factor or condition that can be manipulated or measured in an experiment. It is the element that researchers intentionally alter in order to observe its effect on the outcome or results of the experiment. By changing the variable, researchers can determine the cause and effect relationship between different factors and understand how they influence the experiment.Rate this question:

-
Electrons
Correct Answer
A. ElectronsExplanation
Electrons are negatively charged particles that orbit the nucleus of an atom. They are found on the outside of the nucleus and are responsible for the chemical behavior of atoms. Protons and neutrons are located inside the nucleus and do not carry a negative charge. Kryptonite is a fictional substance and not related to the charges found on an atom's nucleus.Rate this question:
