Q: Answer the following question given this paragraph: The corona is the halo around the Sun. Q: The corona surrounds which major object in our solar system? Choices: - Neptune - Earth's moon - Jupiter - the sun A:
A: the sun

Q: Answer the following question given this paragraph: White Columns Just as the gray matter is separated into horns, the white matter of the spinal cord is separated into columns. Ascending tracts of nervous system fibers in these columns carry sensory information up to the brain, whereas descending tracts carry motor commands from the brain. Looking at the spinal cord longitudinally, the columns extend along its length as continuous bands of white matter. Between the two posterior horns of gray matter are the posterior columns. Between the two anterior horns, and bounded by the axons of motor neurons emerging from that gray matter area, are the anterior columns. The white matter on either side of the spinal cord, between the posterior horn and the axons of the anterior horn neurons, are the lateral columns. The posterior columns are composed of axons of ascending tracts. The anterior and lateral columns are composed of many different groups of axons of both ascending and descending tractsthe latter carrying motor commands down from the brain to the spinal cord to control output to the periphery. Q: The brain is said to contain gray matter, while what related structure contains white matter separated into columns? Choices: - brain stem - amygdala - orbital lobe - spinal cord A:
A: spinal cord

Q: Answer the following question given this paragraph: Salamanders have developed ways not to be eaten. Most salamanders have brightly colored, poisonous skin. The bold color tells predators not to eat the salamander. Many salamanders have glands on the back of the neck or on the tail that give off a poisonous or bad-tasting liquid. Some species can even shed their tail during an attack and grow a new one later. Some salamanders stand high on its legs and waves its tail to scare away danger. One particular salamander, the ribbed newt, has needle-like rib tips. It can squeeze its muscles to make the rib tips pierce through its skin and into its enemy, telling the predator to stay away, a feature unique among the animal kingdom. Q: What features of a salamander's skin help protect itself from predators ? Choices: - camouflaged and thin - slimy and camouflaged - thick and impenetrable - brightly colored and poisonous A:
A: brightly colored and poisonous

Q: Answer the following question given this paragraph: Magnetic Field Produced by a Current-Carrying Solenoid A solenoid is a long coil of wire (with many turns or loops, as opposed to a flat loop). Because of its shape, the field inside a solenoid can be very uniform, and also very strong. The field just outside the coils is nearly zero. Figure 22.40 shows how the field looks and how its direction is given by RHR-2. Q: What current-carrying long coil of wire acts as a magnet? Choices: - converter - antenna - igniter - solenoid A:
A: solenoid
