Question: Passage: Colorado River -- Reduction in flow caused by dams, diversions, water for thermoelectric power stations, and evaporation losses from reservoirs -- the latter of which consumes more than 15 percent of the river's natural runoff -- has had severe ecological consequences in the Colorado River Delta and the Gulf of California. Historically, the delta with its large freshwater outflow and extensive salt marshes provided an important breeding ground for aquatic species in the Gulf. Today's desiccated delta, at only a fraction of its former size, no longer provides suitable habitat, and populations of fish, shrimp and sea mammals in the gulf have seen a dramatic decline. Since 1963, the only times when the Colorado River has reached the ocean have been during El Niño events in the 1980s and 1990s.
Question: does the colorado river still reach the ocean

Answer: 0

Question: Passage: Lorazepam -- Many beneficial effects of lorazepam (e.g., sedative, muscle relaxant, anti-anxiety, and amnesic effects) may become adverse effects when unwanted. Adverse effects can include sedation and low blood pressure; the effects of lorazepam are increased in combination with other CNS depressant drugs. Other adverse effects include confusion, ataxia, inhibiting the formation of new memories, and hangover effects. With long-term benzodiazepine use it is unclear whether cognitive impairments fully return to normal after stopping lorazepam use; cognitive deficits persist for at least six months after withdrawal, but longer than six months may be required for recovery of cognitive function. Lorazepam appears to have more profound adverse effects on memory than other benzodiazepines; it impairs both explicit and implicit memory. In the elderly, falls may occur as a result of benzodiazepines. Adverse effects are more common in the elderly, and they appear at lower doses than in younger patients. Benzodiazepines can cause or worsen depression. Paradoxical effects can also occur, such as worsening of seizures, or paradoxical excitement; paradoxical excitement is more likely to occur in the elderly, children, those with a history of alcohol abuse, and in people with a history of aggression or anger problems. Lorazepam's effects are dose-dependent, meaning the higher the dose, the stronger the effects (and side effects) will be. Using the smallest dose needed to achieve desired effects lessens the risk of adverse effects. Sedative drugs and sleeping pills, including lorazepam, have been associated with an increased risk of death.
