input: OPTIONS:
- hyperopia
- blindness
- astigmatism
- myopia Now, answer this question: Answer the following question given this paragraph: In myopia, the eye is too long. Below, you can see how images are focused on the retina of someone with myopia ( Figure below ). Myopia is corrected with a concave lens, which curves inward like the inside of a bowl. The lens changes the focus, so images fall on the retina as they should. Q: What vision defect occurs because the eye is too long? A:
A:
output: myopia

Answer the following question given this paragraph: Figure 30.4 Leaves are attached to the plant stem at areas called nodes. An internode is the stem region between two nodes. The petiole is the stalk connecting the leaf to the stem. The leaves just above the nodes arose from axillary buds. Q: What is the term for the stalk connecting a leaf to a stem? A:

OPTIONS:
- cuticle
- blades
- base
- petiole

Answer: petiole

Problem: OPTIONS:
- liquid
- volcanic
- core
- crust
Q: Answer the following question given this paragraph: Beneath the crust is the mantle . The mantle is made of hot, solid rock. They know this because of seismic waves, meteorites, and the heat that comes from inside the planet. Mantle rock is mostly peridotite , which is rich in iron and magnesium ( Figure below ). Peridotite is rare at Earth's surface. Q: Made of hot, solid rock, the mantle is beneath what layer of the earth? A:
Answer: crust

Problem:OPTIONS:
- fast glycolytic fibres
- slow twitch fibres
- pores
- myofibrils

Answer the following question given this paragraph: Each muscle fiber contains hundreds of organelles called myofibrils. Each myofibril is made up of two types of protein filaments: actin filaments, which are thinner, and myosin filaments, which are thicker. Actin filaments are anchored to structures called Z lines (see Figure below ). The region between two Z lines is called a sarcomere. Within a sarcomere, myosin filaments overlap the actin filaments. The myosin filaments have tiny structures called cross bridges that can attach to actin filaments. Q: Each muscle fiber contains hundreds of organelles called what? A:
****
A: myofibrils

Answer the following question given this paragraph: Enzymes increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting. One way this can happen is modeled in the Figure below . Enzymes aren't changed or used up in the reactions they catalyze, so they can be used to speed up the same reaction over and over again. Each enzyme is highly specific for the particular reaction is catalyzes, so enzymes are very effective. A reaction that would take many years to occur without its enzyme might occur in a split second with the enzyme. Enzymes are also very efficient, so waste products rarely form. Q: What can be used to accelerate the rate at which chemical reactions occur? A:
OPTIONS:
- hormones
- protein
- components
- enzymes
enzymes

Answer the following question given this paragraph: Most waves approach the shore at an angle. The part of the wave that is nearer the shore reaches shallow water sooner than the part that is farther out. The shallow part of the wave "feels" the bottom first. This slows down the inshore part of the wave and makes the wave "bend. " This bending is called refraction . Q: What three characteristics do waves have? A:
OPTIONS:
- structure , refraction and deflection
- theory , refraction and deflection
- spin, refraction, and deflection
- reflection, refraction and deflection

Answer:
reflection, refraction and deflection
