Correct Answer: Option A
Explanation:
Explanation: The phrase "breakthrough" refers to a significant or important development or discovery, often one that leads to progress or success. In this context, it means that the result of the experiment is a major achievement in medical science.
A. an outstanding success: This is correct. "Breakthrough" denotes a significant achievement or success in the field, especially one that marks progress.
B. catastrophe: This refers to a disastrous event, which is the opposite of a "breakthrough."
C. an end to such experiments: This does not fit, as a "breakthrough" suggests a positive development, not an end to experiments.
D. breaking point: This refers to a moment of crisis or collapse, which is not the meaning of "breakthrough."
E. a colossal failure: This is incorrect, as a "breakthrough" refers to success, not failure.
