Final answer:
The sentence is correctly completed by the words 'believed'; 'clear'; and 'conclusion', which convey Jane's confidence in the evidence of the x-rays and her conclusion about her dog eating her earrings. Option a is the correct answer.
Step-by-step explanation:
To complete the given sentence, we must select the best fitting words that convey a logical and coherent meaning. When choosing the correct completion for the sentence, we need to consider the context and look for clues within the sentence that indicate the relationship between Jane's confidence in her hypothesis and the evidence she had observed. Now, let's analyze the options.
- Believed; clear; conclusion
- Knew; inconclusive; decision
- Assumed; accurate; evidence
- Speculated; vague; results
The correct answer is: Jane believed the x-rays were clear and her conclusion could not be wrong; she knew her hypothesis was correct: her dog had eaten her earrings after all. This selection is the most fitting as it shows a degree of confidence based on evidence, which is 'the x-rays were clear,' indicating a definitive observation rather than speculation. Furthermore, 'her conclusion could not be wrong' integrates well with the preceding affirmation, reflecting a strong belief in the validity of her judgment. This gives us a good understanding of how evidence and conclusions work together in forming a solid hypothesis.
In the sentence, we can also draw a parallel with scientific methodology. Drawing conclusions is a critical step in the scientific process after gathering evidence. It is an informed decision about the hypothesis formulated at the beginning of research or an experiment. In our context, the evidence supports Jane's hypothesis, strengthening her belief in its accuracy, much like how scientific conclusions are reached after multiple evidential affirmations.
The mention of the correct option indeed answers the question asked: Jane believed the x-rays were clear, and her conclusion could not be wrong.
