Input: Article: In 2005, the company sold its personal computer business to Chinese technology company Lenovo, and in the same year it agreed to acquire Micromuse. A year later IBM launched Secure Blue, a low-cost hardware design for data encryption that can be built into a microprocessor. In 2009 it acquired software company SPSS Inc. Later in 2009, IBM's Blue Gene supercomputing program was awarded the National Medal of Technology and Innovation by U.S. President Barack Obama. In 2011, IBM gained worldwide attention for its artificial intelligence program Watson, which was exhibited on Jeopardy! where it won against game-show champions Ken Jennings and Brad Rutter. As of 2012[update], IBM had been the top annual recipient of U.S. patents for 20 consecutive years.

Now answer this question: In what year did IBM sell its personal computer business?

Output: 2005

Input: Article: Bacteriophages are viruses that infect bacteria. Many types of bacteriophage exist, some simply infect and lyse their host bacteria, while others insert into the bacterial chromosome. A bacteriophage can contain genes that contribute to its host's phenotype: for example, in the evolution of Escherichia coli O157:H7 and Clostridium botulinum, the toxin genes in an integrated phage converted a harmless ancestral bacterium into a lethal pathogen. Bacteria resist phage infection through restriction modification systems that degrade foreign DNA, and a system that uses CRISPR sequences to retain fragments of the genomes of phage that the bacteria have come into contact with in the past, which allows them to block virus replication through a form of RNA interference. This CRISPR system provides bacteria with acquired immunity to infection.

Now answer this question: What can viruses do to bacteria?

Output: infect and lyse their host bacteria

Input: Article: The hydraulic crane was invented by Sir William Armstrong in 1846, primarily for use at the Tyneside docks for loading cargo. These quickly supplanted the earlier steam driven elevators: exploiting Pascal's law, they provided a much greater force. A water pump supplied a variable level of water pressure to a plunger encased inside a vertical cylinder, allowing the level of the platform (carrying a heavy load) to be raised and lowered. Counterweights and balances were also used to increase the lifting power of the apparatus.

Now answer this question: In what manner did hydraulic cranes employ Pascal's law? 

Output:
they provided a much greater force
