Question: The initial cost of an incandescent bulb is small compared to the cost of the energy it uses over its lifetime. Incandescent bulbs have a shorter life than most other lighting, an important factor if replacement is inconvenient or expensive. Some types of lamp, including incandescent and fluorescent, emit less light as they age; this may be an inconvenience, or may reduce effective lifetime due to lamp replacement before total failure. A comparison of incandescent lamp operating cost with other light sources must include illumination requirements, cost of the lamp and labor cost to replace lamps (taking into account effective lamp lifetime), cost of electricity used, effect of lamp operation on heating and air conditioning systems. When used for lighting in houses and commercial buildings, the energy lost to heat can significantly increase the energy required by a building's air conditioning system. During the heating season heat produced by the bulbs is not wasted, although in most cases it is more cost effective to obtain heat from the heating system. Regardless, over the course of a year a more efficient lighting system saves energy in nearly all climates.
Try to answer this question if possible: Do incandescent lights have a longer or shorter life than other lighting sources?
Answer: shorter
Question: The modern literary language is usually considered to date from the time of Alexander Pushkin ( ) in the first third of the 19th century. Pushkin revolutionized Russian literature by rejecting archaic grammar and vocabulary (so-called " " "high style") in favor of grammar and vocabulary found in the spoken language of the time. Even modern readers of younger age may only experience slight difficulties understanding some words in Pushkin's texts, since relatively few words used by Pushkin have become archaic or changed meaning. In fact, many expressions used by Russian writers of the early 19th century, in particular Pushkin, Mikhail Lermontov ( ), Nikolai Gogol ( ), Aleksander Griboyedov ( ), became proverbs or sayings which can be frequently found even in modern Russian colloquial speech.
Try to answer this question if possible: What did Lermontov favor instead of archaic grammar and vocabulary?
Answer: unanswerable
Question: The geography of Southampton is influenced by the sea and rivers. The city lies at the northern tip of the Southampton Water, a deep water estuary, which is a ria formed at the end of the last Ice Age. Here, the rivers Test and Itchen converge. The Testwhich has salt marsh that makes it ideal for salmon fishingruns along the western edge of the city, while the Itchen splits Southampton in twoeast and west. The city centre is located between the two rivers.
