Problem: Like other newly independent states of the former Soviet Union, Armenia's economy suffers from the breakdown of former Soviet trading patterns. Soviet investment in and support of Armenian industry has virtually disappeared, so that few major enterprises are still able to function. In addition, the effects of the 1988 Spitak earthquake, which killed more than 25,000 people and made 500,000 homeless, are still being felt. The conflict with Azerbaijan over Nagorno-Karabakh has not been resolved. The closure of Azerbaijani and Turkish borders has devastated the economy, because Armenia depends on outside supplies of energy and most raw materials. Land routes through Georgia and Iran are inadequate or unreliable. The GDP fell nearly 60% between 1989 and 1993, but then resumed robust growth. The national currency, the dram, suffered hyperinflation for the first years after its introduction in 1993.
How much did the Armenian GDP decrease from 1989-1993

Answer: 60%

Problem: Because of their long life, fast switching times, and their ability to be seen in broad daylight due to their high output and focus, LEDs have been used in brake lights for cars' high-mounted brake lights, trucks, and buses, and in turn signals for some time, but many vehicles now use LEDs for their rear light clusters. The use in brakes improves safety, due to a great reduction in the time needed to light fully, or faster rise time, up to 0.5 second faster[citation needed] than an incandescent bulb. This gives drivers behind more time to react. In a dual intensity circuit (rear markers and brakes) if the LEDs are not pulsed at a fast enough frequency, they can create a phantom array, where ghost images of the LED will appear if the eyes quickly scan across the array. White LED headlamps are starting to be used. Using LEDs has styling advantages because LEDs can form much thinner lights than incandescent lamps with parabolic reflectors.
Because of their high output, LED lights are very useful where?

Answer:
brake lights for cars
