Answer the following question given this paragraph: There are approximately 160,000 living species and probably 70,000 extinct species of mollusks. They are typically divided into ten classes, of which two are extinct. The major classes of living mollusks include gastropods, bivalves, and cephalopods ( Figure below ). Q: The major classes of living members of this phylum include gastropods, bivalves, and cephalopods? A:

OPTIONS:
- insects
- crustaceans
- invertebrates
- mollusks

Answer: mollusks

Problem: OPTIONS:
- slippery smear
- dry smear
- oily smear
- slimy smear
Q: Answer the following question given this paragraph: With the naked eye, bacteria just look like a slimy smear on a petri dish. How can we study them in more detail? The invention of the microscope has allowed us to see bacteria, cells, and other things too small to be seen with the naked eye. Q: How does the bacteria look when seen with the naked eye? A:
Answer: slimy smear

Problem:OPTIONS:
- midnight
- opposite times
- different times
- same time

Answer the following question given this paragraph: 28.2 Simultaneity And Time Dilation Two events are defined to be simultaneous if an observer measures them as occurring at the same time. They are not necessarily simultaneous to all observerssimultaneity is not absolute. Time dilation is the phenomenon of time passing slower for an observer who is moving relative to another observer. Observers moving at a relative velocity v do not measure the same elapsed time for an event. Proper time t 0 is the time measured by an observer at rest relative to the event being observed. Proper time is related to the time by an Earth-bound observer by the equation. Q: Two events are defined to be simultaneous if an observer measures them as occurring at what? A:
****
A: same time

Answer the following question given this paragraph: If you've ever seen a kayak move down a fast-moving river, you know that remaining in the same place would be hard. The river current pulls the kayak along. Pushing the oars back against the water can move the kayak forward in the water, but that only accounts for part of the velocity. The kayak's motion is an example of classical addition of velocities. In classical physics, velocities add as vectors. The kayak's velocity is the vector sum of its velocity relative to the water and the water's velocity relative to the riverbank. Q: The kayak's motion in the water is an example of classical addition of what? A:
OPTIONS:
- momentum
- force
- acceleration
- velocities
velocities

Answer the following question given this paragraph: one degree Fahrenheit. Only 100 Celsius degrees span the same range as 180 Fahrenheit degrees, thus one degree on the Celsius scale is 1.8 times larger than one degree on the Fahrenheit scale 180 / 100 = 9 / 5. The Kelvin scale is the temperature scale that is commonly used in science. It is an absolute temperature scale defined to have 0 K at the lowest possible temperature, called absolute zero. The official temperature unit on this scale is the kelvin, which is abbreviated K, and is not accompanied by a degree sign. The freezing and boiling points of water are 273.15 K and 373.15 K, respectively. Thus, the magnitude of temperature differences is the same in units of kelvins and degrees Celsius. Unlike other temperature scales, the Kelvin scale is an absolute scale. It is used extensively in scientific work because a number of physical quantities, such as the volume of an ideal gas, are directly related to absolute temperature. The kelvin is the SI unit used in scientific work. Q: Which temperature scale is commonly used in science? A:
OPTIONS:
- ph scale
- celsius
- centigrade
- kelvin scale

Answer: kelvin scale

input with options: Answer the following question given this paragraph: An atomic orbital is a region of space around an atom that has a non-zero probability for an electron with a particular energy. Analogously, a molecular orbital is a region of space in a molecule that has a non-zero probability for an electron with a particular energy. Both an atomic orbital and a molecular orbital can contain two electrons. Q: What term describes a region of space around an atom that has a non-zero probability for an electron with a particular energy? A:
OPTIONS:
- orbital lobe
- minimal orbital
- related orbital
- atomic orbital
output:
atomic orbital
