Problem: Separation of powers under the United States Constitution:

Throughout America's history dominance of one of the three branches has essentially been a see-saw struggle between Congress and the president. Both have had periods of great power and weakness such as immediately after the Civil War when republicans had a majority in Congress and were able to pass major legislation and shoot down most of the president's vetoes. They also passed acts to essentially make the president subordinate to Congress, such as the Tenure of Office Act. Johnson's later impeachment also cost the presidency much political power. However the president has also exercised greater power largely during the 20th century. Both Roosevelts greatly expanded the powers of the president and wielded great power during their terms.

After which war did Republicans hold a minority in Congress?

Problem: 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 color will acid-fast bacilli become when stained?

Answer: bright red

The other large cemeteries are the Cementerio del Buceo, Cementerio del Cerro, and Cementerio Paso Molino. The British Cemetery Montevideo (Cementerio Britanico) is another of the oldest cemeteries in Uruguay, located in the Buceo neighborhood. Many noblemen and eminent persons are buried there. The cemetery originated when the Englishman Mr. Thomas Samuel Hood purchased a plot of land in the name of the English residents in 1828. However, in 1884 the government compensated the British by moving the cemetery to Buceo to accommodate city growth. A section of the cemetery, known as British Cemetery Montevideo Soldiers and Sailors, contains the graves of quite a number of sailors of different nationalities, although the majority are of British descent. One United States Marine, Henry de Costa, is buried here.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did Mr. Thomas Samuel Hood purchase a plot of land at the British Cemetery Montevideo?
Ah, so..
1828
