Problem: On 3 May 1505 King Alexander I Jagiellon granted the Act of "Nihil novi nisi commune consensu" (Latin: "I accept nothing new except by common consent"). This forbade the king to pass any new law without the consent of the representatives of the nobility, in Sejm and Senat assembled, and thus greatly strengthened the nobility's political position. Basically, this act transferred legislative power from the king to the Sejm. This date commonly marks the beginning of the First Rzeczpospolita, the period of a szlachta-run "Commonwealth".
Who granted the act Act of "Nihil novi nisi commune consensu"?
The answer is the following: King Alexander I Jagiellon

Problem: Montana contains thousands of named rivers and creeks, 450 miles (720 km) of which are known for "blue-ribbon" trout fishing. Montana's water resources provide for recreation, hydropower, crop and forage irrigation, mining, and water for human consumption. Montana is one of few geographic areas in the world whose rivers form parts of three major watersheds (i.e. where two continental divides intersect). Its rivers feed the Pacific Ocean, the Gulf of Mexico, and Hudson Bay. The watersheds divide at Triple Divide Peak in Glacier National Park.
Where do the watersheds divide at?
The answer is the following: Triple Divide Peak in Glacier National Park.

Problem: Kingdom Plantae belongs to Domain Eukarya and is broken down recursively until each species is separately classified. The order is: Kingdom; Phylum (or Division); Class; Order; Family; Genus (plural genera); Species. The scientific name of a plant represents its genus and its species within the genus, resulting in a single world-wide name for each organism. For example, the tiger lily is Lilium columbianum. Lilium is the genus, and columbianum the specific epithet. The combination is the name of the species. When writing the scientific name of an organism, it is proper to capitalise the first letter in the genus and put all of the specific epithet in lowercase. Additionally, the entire term is ordinarily italicised (or underlined when italics are not available).
What part of the name is always capitalized?
The answer is the following: the genus

Problem: There are 29 isotopes of copper. 63Cu and 65Cu are stable, with 63Cu comprising approximately 69% of naturally occurring copper; they both have a spin of 32. The other isotopes are radioactive, with the most stable being 67Cu with a half-life of 61.83 hours. Seven metastable isotopes have been characterized, with 68mCu the longest-lived with a half-life of 3.8 minutes. Isotopes with a mass number above 64 decay by , whereas those with a mass number below 64 decay by +. 64Cu, which has a half-life of 12.7 hours, decays both ways.
Which isotope makes up about 69% of natural copper?
The answer is the following:
63Cu
