Context: In addition to the classical restaurants, Paris has several other kinds of traditional eating places. The cafe arrived in Paris in the 17th century, when the beverage was first brought from Turkey, and by the 18th century Parisian cafes were centres of the city's political and cultural life. The Cafe Procope on the Left Bank dates from this period. In the 20th century, the cafes of the Left Bank, especially Cafe de la Rotonde and Le Dome Cafe in Montparnasse and Cafe de Flore and Les Deux Magots on Boulevard Saint Germain, all still in business, were important meeting places for painters, writers and philosophers. A bistro is a type of eating place loosely defined as a neighbourhood restaurant with a modest decor and prices and a regular clientele and a congenial atmosphere. Its name is said to have come in 1814 from the Russian soldiers who occupied the city; "bistro" means "quickly" in Russian, and they wanted their meals served rapidly so they could get back their encampment. Real bistros are increasingly rare in Paris, due to rising costs, competition from cheaper ethnic restaurants, and different eating habits of Parisian diners. A brasserie originally was a tavern located next to a brewery, which served beer and food at any hour. Beginning with the Paris Exposition of 1867; it became a popular kind of restaurant which featured beer and other beverages served by young women in the national costume associated with the beverage, particular German costumes for beer. Now brasseries, like cafes, serve food and drinks throughout the day.

Question: It can be concluded that the desalination plant in Wonthaggi and the pipelines projects are not as effective as what? Context: Melbourne's air quality is generally good and has improved significantly since the 1980s. Like many urban environments, the city faces significant environmental issues, many of them relating to the city's large urban footprint and urban sprawl and the demand for infrastructure and services. One such issue is water usage, drought and low rainfall. Drought in Victoria, low rainfalls and high temperatures deplete Melbourne water supplies and climate change may have a long-term impact on the water supplies of Melbourne. In response to low water supplies and low rainfall due to drought, the government implemented water restrictions and a range of other options including: water recycling schemes for the city, incentives for household water tanks, greywater systems, water consumption awareness initiatives, and other water saving and reuse initiatives; also, in June 2007, the Bracks Government announced that a $3.1 billion Wonthaggi desalination plant would be built on Victoria's south-east coast, capable of treating 150 billion litres of water per year, as well as a 70 km (43 mi) pipeline from the Goulburn area in Victoria's north to Melbourne and a new water pipeline linking Melbourne and Geelong. Both projects are being conducted under controversial Public-Private Partnerships and a multitude of independent reports have found that neither project is required to supply water to the city and that Sustainable Water Management is the best solution. In the meantime, the drought must be weathered.

input: Please answer the following: Extract the answer to the question from the following context. Question: What is required to happen after the H2O changed from a liquid to a vapor? Context: After boiling, the hopped wort is now cooled, ready for the yeast. In some breweries, the hopped wort may pass through a hopback, which is a small vat filled with hops, to add aromatic hop flavouring and to act as a filter; but usually the hopped wort is simply cooled for the fermenter, where the yeast is added. During fermentation, the wort becomes beer in a process which requires a week to months depending on the type of yeast and strength of the beer. In addition to producing ethanol, fine particulate matter suspended in the wort settles during fermentation. Once fermentation is complete, the yeast also settles, leaving the beer clear.

output: the hopped wort is now cooled

input: Please answer the following: Extract the answer to the question from the following context. Question: If you need a low slope, what do you use? Context: LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.

Red LEDs
