Here is a question about this article: The last opus number that Chopin himself used was 65, allocated to the Cello Sonata in G minor. He expressed a deathbed wish that all his unpublished manuscripts be destroyed. At the request of the composer's mother and sisters, however, his musical executor Julian Fontana selected 23 unpublished piano pieces and grouped them into eight further opus numbers (Opp. 6673), published in 1855. In 1857, 17 Polish songs that Chopin wrote at various stages of his life were collected and published as Op. 74, though their order within the opus did not reflect the order of composition.
What is the answer to this question: What is the last opus number that Chopin used?
****
So... 65

Here is a question about this article: Using histological stains on expectorated samples from phlegm (also called "sputum"), scientists can identify MTB under a microscope. Since MTB retains certain stains even after being treated with acidic solution, it is classified as an acid-fast bacillus. The most common acid-fast staining techniques are the ZiehlNeelsen stain and the Kinyoun stain, which dye acid-fast bacilli a bright red that stands out against a blue background. Auramine-rhodamine staining and fluorescence microscopy are also used.
What is the answer to this question: One of the two standard acid-fast staining techniques is the Kinyoun stain; what's the other?
****
So... ZiehlNeelsen stain

Here is a question about this article: A major international priority for Tuvalu in the UN, at the 2002 Earth Summit in Johannesburg, South Africa and in other international fora, is promoting concern about global warming and the possible sea level rising. Tuvalu advocates ratification and implementation of the Kyoto Protocol. In December 2009 the islands stalled talks on climate change at the United Nations Climate Change Conference in Copenhagen, fearing some other developing countries were not committing fully to binding deals on a reduction in carbon emissions. Their chief negotiator stated, "Tuvalu is one of the most vulnerable countries in the world to climate change and our future rests on the outcome of this meeting."
What is the answer to this question: What agreement does Tuvalu advocate ratification?
****
So...
Kyoto Protocol
