Input: Article: High-power LEDs (HP-LEDs) or high-output LEDs (HO-LEDs) can be driven at currents from hundreds of mA to more than an ampere, compared with the tens of mA for other LEDs. Some can emit over a thousand lumens. LED power densities up to 300 W/cm2 have been achieved. Since overheating is destructive, the HP-LEDs must be mounted on a heat sink to allow for heat dissipation. If the heat from a HP-LED is not removed, the device will fail in seconds. One HP-LED can often replace an incandescent bulb in a flashlight, or be set in an array to form a powerful LED lamp.

Now answer this question: What can one high-power LED replace?

Output: incandescent bulb in a flashlight

Input: Article: South America became linked to North America through the Isthmus of Panama during the Pliocene, bringing a nearly complete end to South America's distinctive marsupial faunas. The formation of the Isthmus had major consequences on global temperatures, since warm equatorial ocean currents were cut off and an Atlantic cooling cycle began, with cold Arctic and Antarctic waters dropping temperatures in the now-isolated Atlantic Ocean. Africa's collision with Europe formed the Mediterranean Sea, cutting off the remnants of the Tethys Ocean. Sea level changes exposed the land-bridge between Alaska and Asia. Near the end of the Pliocene, about 2.58 million years ago (the start of the Quaternary Period), the current ice age began. The polar regions have since undergone repeated cycles of glaciation and thaw, repeating every 40,000–100,000 years.

Now answer this question: What is the link between North and South America called?

Output: the Isthmus of Panama

Input: Article: Nevertheless, whether and to what degree any of these types of intermediaries have secondary liability is the subject of ongoing litigation. The decentralised structure of peer-to-peer networks, in particular, does not sit easily with existing laws on online intermediaries' liability. The BitTorrent protocol established an entirely decentralised network architecture in order to distribute large files effectively. Recent developments in peer-to-peer technology towards more complex network configurations are said to have been driven by a desire to avoid liability as intermediaries under existing laws.

Now answer this question: What was the initial purpose of the BitTorrent protocol?

Output:
distribute large files effectively
