The length of AR would be 8cm since 20-12=8 and 12+8=20
Science is not testable is not a characteristic of science.
The omitted options include :
- science is a process.
- science is a body of knowledge.
- science must follow the scientific method.
- science is not testable.
<h3>What is a Scientific method? </h3>
A scientific method refers to the step by step process that scientists must follow in order to give scientific explanation of a phenomena or invention of an idea that is testable.
The scientific method includes:
- Observation
- Constructing a hypothesis/ testable explanation
- Conducting experiments to test the hpothesis
- Formulation of theories based on experiments
- Conducting further experiments and research
- Making conclusions/Formulation of laws.
- Reporting, and evaluating.
Thus, the characteristics of science include:
- science is a process.
- science is a body of knowledge.
- science must follow the scientific method.
Therefore it is wrong to say that science is not testable.

The reason why the presence of dusty disks were surprising is because; A) such systems could not have formed planets.
<h3>
What is a dusty disk?</h3>
A dusty disk is a circumstellar disk of dust and debris found in the orbit around a star and sometimes these disks contain prominent rings.
Now, these disks around young stars are made up of 99% gas and 1% dust and this small amount of dust is still sufficient to make the disks opaque and dark at visible wavelengths.
Now, the dust may be 1% but it is 1 million times more than that found in our solar planets and it orbits at a distance from the star that is similar to the orbits of Earth and Venus around our own Sun.
The missing options are;
A) such systems could not have formed planets.
B) their composition differs so much from their stars.
C) their instruments were not thought to be powerful enough to make such a measurement.
D) gas and dust should be rapidly ejected into space by the radiation from a hot star.
