Answer the following question given this paragraph: The above example shows how science generally advances. New evidence is usually used to improve earlier ideas rather than entirely replace them. In this way, scientists gradually refine their ideas and increase our understanding of the world. On the other hand, sometimes science advances in big leaps. This has happened when a scientist came up with a completely new way of looking at things. For example, Albert Einstein came up with a new view of gravity. He said it was really just a dent in the fabric of space and time. Q: Representing a leap in scientific understanding, einstein described what as a dent in the fabric of space and time? A:

OPTIONS:
- motion
- light
- energy
- gravity

Answer: gravity

Problem: OPTIONS:
- ten
- five
- four
- three
Q: Answer the following question given this paragraph: Remember the quarks from the first page of this chapter? Quarks are even tinier particles of matter that make up protons and neutrons. There are three quarks in each proton and three quarks in each neutron. The charges of quarks are balanced exactly right to give a positive charge to a proton and a neutral charge to a neutron. It might seem strange that quarks are never found alone but only as components of other particles. This is because the quarks are held together by very strange particles called gluons. Q: How many quarks are in each proton and neutron? A:
Answer: three

Problem:OPTIONS:
- the boy
- neither will land
- the elephant
- both same time

Answer the following question given this paragraph: Both the elephant and the boy are falling to the ground because of gravity. The force of gravity (F grav ) is greater for the elephant than it is for the boy because the elephant is much more massive. Nonetheless, both of them will reach the ground at the same time (assuming they fall from the same height at the same time and there is no air resistance. ). Q: If an elephant and a boy are falling towards the ground, who will land first? A:
****
A: both same time

Answer the following question given this paragraph: The primary cause of tides is the gravitational attraction of the Moon. This causes two high and two low tides a day. Q: How many low and high tides occur per day? A:
OPTIONS:
- six
- ten
- four
- two
two

Answer the following question given this paragraph: Igneous rocks are classified first by composition. Categories go from from felsic to ultramafic. Color can indicate composition. Q: What is the first classification of igneous rocks? A:
OPTIONS:
- size
- color
- weight
- composition

Answer: composition

input with options: Answer the following question given this paragraph: Some lipids contain the element phosphorus as well as oxygen, carbon, and hydrogen. These lipids are called phospholipids. Two layers of phospholipid molecules make up most of the cell membrane in the cells of living things. Q: What are lipids that contain phosphorus called? A:
OPTIONS:
- amino acids
- alkaloids
- eukaryotes
- phospholipids
output:
phospholipids
