Q: Answer the following question given this paragraph: Astronomers use many tools to study things in space. Earth-orbiting telescopes view stars and galaxies from the darkness of space ( Figure below ). They may have optical and radio telescopes to see things that the human eye can't see. Spacecraft travel great distances to send back information on faraway places. Q: What type of scientist uses earth-orbiting telescopes? A:

OPTIONS:
- astrologer
- biologist
- anthropologist
- astronomer

A: astronomer

input: OPTIONS:
- thermal energy
- microwaves
- isotopes
- electrical signal Now, answer this question: Answer the following question given this paragraph: Solid-state radiation detectors convert ionization produced in a semiconductor (like those found in computer chips) directly into an electrical signal. Semiconductors can be constructed that do not conduct current in one particular direction. When a voltage is applied in that direction, current flows only when ionization is produced by radiation, similar to what happens in a Geiger tube. Further, the amount of current in a solid-state detector is closely related to the energy deposited and, since the detector is solid, it can have a high efficiency (since ionizing radiation is stopped in a shorter distance in solids fewer particles escape detection). As with scintillators, very sophisticated information can be obtained from solid-state detectors. PhET Explorations: Radioactive Dating Game Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating to work. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object. Q: Solid-state radiation detectors convert ionization produced in a semiconductor (like those found in computer chips) directly into what? A:
A:
output: electrical signal

Answer the following question given this paragraph: Head hair protects the scalp from ultraviolet light exposure and loss of body heat. Hair in eyelashes, eyebrows, and nostrils traps water, dust, and other irritants. Nails protect the ends of fingers and toes and enhance the sense of touch. Q: What protects the scalp from ultraviolet light exposure and loss of body heat? A:

OPTIONS:
- ground hair
- temporal hair
- receding hair
- head hair

Answer: head hair

Problem: OPTIONS:
- anally
- biologically
- asexually
- sexually
Q: Answer the following question given this paragraph: Vertebrates reproduce sexually. Most have separate male and female sexes. Vertebrates have one of three reproductive strategies: ovipary, ovovivipary, or vivipary. Q: In which way to vertebrates reproduces? A:
Answer: sexually

Problem:OPTIONS:
- human fibers
- use fibers
- job fibers
- muscle fibers

Answer the following question given this paragraph: The muscular system consists of all the muscles of the body. Muscles are organs composed mainly of muscle cells, which are also called muscle fibers . Each muscle fiber is a very long, thin cell that can do something no other cell can do. It can contract, or shorten. Muscle contractions are responsible for virtually all the movements of the body, both inside and out. There are three types of muscle tissues in the human body: cardiac, smooth, and skeletal muscle tissues. They are shown in Figure below and described below. Q: What are muscle cells in the muscles called? A:
****
A: muscle fibers

Problem:OPTIONS:
- the epicenter
- the tectonic plate
- the fault
- the focus

Answer the following question given this paragraph: The focus of an earthquake is in the ground where the ground breaks. The epicenter is the point at the surface just above the focus. Q: Which part of an earthquake is in the ground where the ground breaks? A:
****
A:
the focus
