Most species of plants can survive short dry periods without serious injury, but a prolonged period of soil water deficiency is highly injurious or lethal to all except those species of plants with a well-developed capacity for drought resistance... A fundamental factor in the drought resistance of plants therefore appears to be a capacity of the cells to endure a substantial reduction in their water content without suffering injury. 3, record 1, English, - drought%20resistance

When a taxi driver of an unoccupied taxi is seeking passengers on a road unknown to him or her in a large city, what should the driver do? Alternatives include cruising around the road or waiting for a time period at the roadside in the hopes of finding a passenger or just leaving for another road enroute to a destination he [or she] knows(e. g., hotel taxi rank) ?... There could be different answers to the question poised above, but one fundamental problem is how the driver learns about the likelihood of finding passengers on a road that is new to him [or her. ] 7, record 2, English, - unoccupied%20taxi
