Problem: Please answer a question about the following article about Elevator:
During up-peak mode (also called moderate incoming traffic), elevator cars in a group are recalled to the lobby to provide expeditious service to passengers arriving at the building, most typically in the morning as people arrive for work or at the conclusion of a lunch-time period. Elevators are dispatched one-by-one when they reach a pre-determined passenger load, or when they have had their doors opened for a certain period of time. The next elevator to be dispatched usually has its hall lantern or a "this car leaving next" sign illuminated to encourage passengers to make maximum use of the available elevator system capacity. Some elevator banks are programmed so that at least one car will always return to the lobby floor and park whenever it becomes free.
For what reasons are elevators routed one-by-one?
A: when they reach a pre-determined passenger load, or when they have had their doors opened for a certain period of time

Problem: Although initially the Germans were welcomed by most Estonians as liberators from the USSR and its oppressions, and hopes were raised for the restoration of the country's independence, it was soon realised that the Nazis were but another occupying power. The Germans used Estonia's resources for their war effort; for the duration of the occupation Estonia was incorporated into the German province of Ostland. The Germans and their collaborators also carried out The Holocaust in Estonia in which they established a network of concentration camps and murdered thousands of Estonian Jews and Estonian Gypsies, other Estonians, non-Estonian Jews, and Soviet prisoners of war.
What did Germany take from Estonia for their war strategy?
The answer is the following: Estonia's resources


Several molecular mechanisms of antibacterial resistance exist. Intrinsic antibacterial resistance may be part of the genetic makeup of bacterial strains. For example, an antibiotic target may be absent from the bacterial genome. Acquired resistance results from a mutation in the bacterial chromosome or the acquisition of extra-chromosomal DNA. Antibacterial-producing bacteria have evolved resistance mechanisms that have been shown to be similar to, and may have been transferred to, antibacterial-resistant strains. The spread of antibacterial resistance often occurs through vertical transmission of mutations during growth and by genetic recombination of DNA by horizontal genetic exchange. For instance, antibacterial resistance genes can be exchanged between different bacterial strains or species via plasmids that carry these resistance genes. Plasmids that carry several different resistance genes can confer resistance to multiple antibacterials. Cross-resistance to several antibacterials may also occur when a resistance mechanism encoded by a single gene conveys resistance to more than one antibacterial compound.
What can be absent from the bacterial genome?
antibiotic target

In 1862, paper money was issued without the backing of precious metals, due to the Civil War. Silver and gold coins continued to be issued and in 1878 the link between paper money and coins was reinstated. This disconnection from gold and silver backing also occurred during the War of 1812. The use of paper money not backed by precious metals had also occurred under the Articles of Confederation from 1777 to 1788. With no solid backing and being easily counterfeited, the continentals quickly lost their value, giving rise to the phrase "not worth a continental". This was a primary reason for the "No state shall... make any thing but gold and silver coin a tender in payment of debts" clause in article 1, section 10 of the United States Constitution.

Which year was it when paper money was first issued without the backing of precious metals?
Output: 1777
