Problem: In 1845, Ireland was hit by a potato blight. In the next four years over a million Irish people died and another million emigrated in what became known as the Great Famine. In Ireland, Victoria was labelled "The Famine Queen". She personally donated £2,000 to famine relief, more than any other individual donor, and also supported the Maynooth Grant to a Roman Catholic seminary in Ireland, despite Protestant opposition. The story that she donated only £5 in aid to the Irish, and on the same day gave the same amount to Battersea Dogs Home, was a myth generated towards the end of the 19th century.
How long did the Great Famine last?
The answer is the following: four years

Problem: Genetic studies of mitochondrial DNA (mtDNA) of Amerindians and some Siberian and Central Asian peoples also revealed that the gene pool of the Turkic-speaking peoples of Siberia such as Altaians, Khakas, Shors and Soyots, living between the Altai and Lake Baikal along the Sayan mountains, are genetically closest to Amerindians.[citation needed] This view is shared by other researchers who argue that "the ancestors of the American Indians were the first to separate from the great Asian population in the Middle Paleolithic. 2012 research found evidence for a recent common ancestry between Native Americans and indigenous Altaians based on mitochondrial DNA and Y-Chromosome analysis. The paternal lineages of Altaians mostly belong to the subclades of haplogroup P-M45 (xR1a 38-93%; xQ1a 4-32%).
What DNA analysis indicated the common ancestry of the Native Americans?
The answer is the following: mitochondrial DNA and Y-Chromosome

Problem: The genome size, and the number of genes it encodes varies widely between organisms. The smallest genomes occur in viruses (which can have as few as 2 protein-coding genes), and viroids (which act as a single non-coding RNA gene). Conversely, plants can have extremely large genomes, with rice containing >46,000 protein-coding genes. The total number of protein-coding genes (the Earth's proteome) is estimated to be 5 million sequences.
Which organism acts as a single non coding RNA gene?
The answer is the following: viroids

Problem: To aid customers with defective consoles, Microsoft extended the Xbox 360's manufacturer's warranty to three years for hardware failure problems that generate a "General Hardware Failure" error report. A "General Hardware Failure" is recognized on all models released before the Xbox 360 S by three quadrants of the ring around the power button flashing red. This error is often known as the "Red Ring of Death". In April 2009 the warranty was extended to also cover failures related to the E74 error code. The warranty extension is not granted for any other types of failures that do not generate these specific error codes.
Where did users see the flashing light error codes display on their 360s?
The answer is the following:
the ring around the power button
