The term "falsifiability" means
- A.
The faking of experimental results.
- B.
The ability to disprove a particular claim.
- C.
The ability to prove a particular claim.
Correct Answer
B. The ability to disprove a particular claim.Explanation
Falsifiability refers to the ability to disprove a particular claim. It is a concept in scientific research that states for a hypothesis or theory to be considered valid, it must be possible to conceive of an experiment or observation that could potentially show it to be false. In other words, a claim is only considered scientific if it can be tested and potentially proven wrong. This principle is essential for maintaining the integrity and objectivity of scientific inquiry.Rate this question:

A good hypothesis can be best described as
- A.
A set of observations.
- B.
A theory that has not been proved yet.
- C.
An educated guess that accounts for all observations whilst predicting future ones.
Correct Answer
C. An educated guess that accounts for all observations whilst predicting future ones.Explanation
A good hypothesis can be best described as an educated guess that accounts for all observations whilst predicting future ones. This means that a hypothesis is not just a random guess, but rather a logical and informed explanation that takes into consideration all the available data. It should also have the ability to make predictions about future observations, allowing for further testing and validation.Rate this question:

Extraordinary claims require extraordinary ______________.
Correct Answer
evidenceExplanation
Extraordinary claims are statements that go against common knowledge or beliefs and are therefore unlikely to be accepted without strong supporting evidence. The phrase "extraordinary claims require extraordinary evidence" emphasizes the need for evidence that is substantial, compelling, and beyond what would be expected for ordinary claims. This principle suggests that the burden of proof is higher for extraordinary claims, as they challenge established understanding and demand more convincing evidence to be considered credible.Rate this question:

Albert Einstein developed a modern understanding of gravity, called
- A.
Gravitational theory.
- B.
Special relativity.
- C.
General relativity
- D.
Relative generality.
Correct Answer
C. General relativityExplanation
Albert Einstein developed the theory of general relativity, which is a modern understanding of gravity. This theory explains gravity as the curvature of spacetime caused by the presence of mass and energy. It is a more comprehensive and accurate explanation of gravity compared to the previous Newtonian theory. Special relativity, on the other hand, deals with the behavior of objects moving at high speeds and does not specifically address gravity. Relative generality is not a recognized scientific concept.Rate this question:

For science to be possible, the following assumption must be made:
- A.
Human beings are intelligent enough to understand the way nature works.
- B.
Nature has order and works according to fixed laws.
- C.
Scientists only publish accurate and honest results.
Correct Answer
B. Nature has order and works according to fixed laws.Explanation
The assumption that nature has order and works according to fixed laws is crucial for the possibility of science. This assumption implies that there are consistent patterns and regularities in the natural world that can be observed, measured, and understood. Without this assumption, scientific inquiry would be futile, as there would be no predictable cause-and-effect relationships or principles to investigate. The belief in the orderliness of nature allows scientists to formulate hypotheses, conduct experiments, and make reliable predictions, forming the foundation of scientific knowledge and progress.Rate this question:

- A.
Ensure that the results obtained are the ones that were hypothesized.
- B.
Increase the overall accuracy of the measurements taken in the experiment.
- C.
Minimize the effects all the variables except the one being investigated.
Correct Answer
C. Minimize the effects all the variables except the one being investigated.Explanation
The function of a control in a scientific experiment is to minimize the effects of all variables except the one being investigated. This is important because it allows researchers to isolate and understand the specific impact of the variable they are studying. By keeping all other variables constant, the control group provides a baseline against which the experimental group can be compared. This helps ensure that any observed changes or effects can be attributed to the variable being investigated rather than other factors.Rate this question:
