Concept introduction: Science refers to the practical and intellectual activity going around the systematic study of behavior and structure of the natural and physical world through observation and experiment. The concept of science explains about the systematic and testable explanation about the universe.

Answer to Problem 1SQ
Correct answer: Scientific hypothesis is an educated guess explaining an observation. Therefore, option a. is correct answer.
Explanation of Solution
Reason for the correct statement:
Option a. is given as “an educated guess explaining an observation”.
Scientific hypothesis is a logical, informal, and plausible explanation for the observation of the natural world. This is often identified as the educated guess that seeks and describes the observed phenomenon. A fully explained scientific hypothesis is a clear-cut prediction that is necessary for testing the particular hypothesis.
Hence, option a. is the correct answer
Reasons for the incorrect statement:
Option b. is given as “a prediction based on an observation”. Prediction based observation have both positive and negative conclusion. But hypothesis needs particular conclusion. Hence, option b. is incorrect.
Option c. is given as “a scientific theory”. A scientific theory is a comprehensive explanation to prove a hypothesis, which is a predictive statement. It is based on a set of experiments and observations. Scientific theories can be revised upon the discovery of new data. Hence, option c. is incorrect.
Option d. is given as “an idea that can be proved beyond all doubt through experimentation.” Hypothesis is a reasoned prediction that is based on certain assumptions. It is a precise statement that needs to be tested with more observations and experiments. Hence, option d. is incorrect.
Hence, options b., c., and d. are incorrect.
