A premise is given below, followed by three statements which may or may not be assumptions on which the passage lies. From the options below, choose the one that reflects the correct choice of assumptions that follow. Passage: Researchers in Japan successfully utilized a synthetic protein to reverse age-related cognitive decline in laboratory mice, observing significant improvements in memory and problem-solving speed. According to the report in Nature Aging, this breakthrough confirms that the synthetic protein is a definitive cure for cognitive deterioration in the aging human population. Statements: 1. The physiological response of the mouse brain to the synthetic protein is a reliable indicator of the response in the human brain. 2. The reversal of cognitive decline observed in the study is a lasting effect rather than a temporary spike in brain activity. 3. Cognitive decline in both mice and humans is primarily triggered by the same environmental stressors.
