Q: Answer the following question given this paragraph: Now we move on to recycle. Sometimes it may be difficult to understand the differences between reusing and recycling. Recycling involves processing used materials in order to make them suitable for other uses. That usually means taking a used item, breaking it down, and reusing the pieces. Even though recycling requires extra energy, it does often make use of items which are broken, worn out, or cannot be reused. Q: What is the process of processing used material into new ones called? A:

OPTIONS:
- remake
- renew
- reuse
- recycling

A: recycling

input: OPTIONS:
- gravitational
- motion
- tension
- friction Now, answer this question: Answer the following question given this paragraph: Every surface has microscopic bumps, lumps, and imperfections, emphasized as in the image above. If we try to slide the top block over the lower block, there will be numerous collisions as the bumps impact each other. The forward motion causes the collisions with bumps which then exert a force in opposite way the block is moving. The force of friction always opposes whatever motion is causing the friction. Q: What force is caused by microscopic bumps, lumps, and imperfections colliding? A:
A:
output: friction

Answer the following question given this paragraph: The thymus is located in the upper chest behind the breast bone. It stores and matures lymphocytes. Q: Which lymphoid organ is situated in the upper chest? A:

OPTIONS:
- thyroid gland
- spleen
- pancreas
- thymus

Answer: thymus

Problem: OPTIONS:
- deformation
- decomposition
- dissolution
- dissociation
Q: Answer the following question given this paragraph: An ionic crystal lattice breaks apart when it is dissolved in water. Dissociation is the separation of ions that occurs when a solid ionic compound dissolves. It is important to be able to write dissociation equations. Simply undo the crisscross method that you learned when writing chemical formulas of ionic compounds. The subscripts for the ions in the chemical formulas become the coefficients of the respective ions on the product side of the equation. Shown below are dissociation equations for NaCl, Ca(NO 3 ) 2 , and (NH 4 ) 3 PO 4 . Q: What do you call the separation of ions that occurs when a solid ionic compound dissolves? A:
Answer: dissociation

Problem:OPTIONS:
- dominant
- fatal
- adaptive
- sex-linked

Answer the following question given this paragraph: One example of a sex-linked trait is red-green colorblindness. People with this type of colorblindness cannot tell the difference between red and green. They often see these colors as shades of brown ( Figure below ). Boys are much more likely to be colorblind than girls ( Table below ). This is because colorblindness is a sex-linked, recessive trait. Q: Red-green colorblindness is an example of what kind of trait? A:
****
A: sex-linked

Problem:OPTIONS:
- magnetic
- seismic
- thermal
- kinetic

Answer the following question given this paragraph: Figure 10.18 The first image shows how helicopters store large amounts of rotational kinetic energy in their blades. This energy must be put into the blades before takeoff and maintained until the end of the flight. The engines do not have enough power to simultaneously provide lift and put significant rotational energy into the blades. The second image shows a helicopter from the Auckland Westpac Rescue Helicopter Service. Over 50,000 lives have been saved since its operations beginning in 1973. Here, a water rescue operation is shown. (credit: 111 Emergency, Flickr). Q: Helicopters store large amounts of rotational energy of what type in their blades? A:
****
A:
kinetic
