Read the passage below and identify which of the following statements (1, 2, and 3) can be logically inferred. Select the correct combination from the options provided. Passage: Studies suggest that the consistent use of digital navigation tools is associated with a reduction in the volume of the hippocampus—the brain region responsible for spatial memory and navigation—in young adults. This neurological shift could potentially lead to a gradual decline in the population's ability to navigate complex environments without digital assistance over the next few generations. In 2021, a team of researchers in Tokyo observed a similar correlation between GPS dependency and reduced spatial awareness in their local test subjects. Statements: 1. Environmental navigation and spatial memory are processes influenced by biological structures. 2. The younger generation in Tokyo might struggle more with physical map-reading compared to previous generations. 3. The neurological shift in the hippocampus is solely caused by the blue light emitted from digital navigation screens.
