You will be given a passage, and your task is to generate a Yes/No question that is answerable based on the given passage.

[EX Q]: LED grow lights vary in color depending on the intended use. It is known from the study of photomorphogenesis that green, red, far-red and blue light spectra have an effect on root formation, plant growth, and flowering, but there are not enough scientific studies or field-tested trials using LED grow lights to recommended specific color ratios for optimal plant growth under LED grow lights. It has been shown that many plants will grow normally if given both red and blue light. However, many studies indicate that red and blue light only provides the most cost efficient method of growth, plant growth is still better under light supplemented with green.
[EX A]: do red and blue led grow lights work?

[EX Q]: The colour orange is named after the appearance of the ripe orange fruit. The word comes from the Old French orange, from the old term for the fruit, pomme d'orange. The French word, in turn, comes from the Italian arancia, based on Arabic nāranj, derived from the Sanskrit naranga. The first recorded use of orange as a colour name in English was in 1512, in a will now filed with the Public Record Office.
[EX A]: was the color orange named after the fruit?

[EX Q]: 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.
[EX A]:
does the colorado river make it to the ocean?
