In the context of the passage which of the following is not true? Water should be central to our thinking because:

The passage explicitly states 'Water is the core of life' (option 4 is true) and emphasizes water's centrality to life and farming (options 1 and 2 are reasonable inferences). However, the passage does NOT discuss water being 'considered holy by most religions'. While the passage mentions spirituality in passing ('water must be central to our spiritual thinking'), it does not claim that most religions consider water holy. Hence option 3 is not supported by the passage.
