Problem: George VI:

In a time when royals were expected to marry fellow royals, it was unusual that Albert had a great deal of freedom in choosing a prospective wife. An infatuation with the already-married Australian socialite Sheila, Lady Loughborough, came to an end in April 1920 when the King, with the promise of the dukedom of York, persuaded Albert to stop seeing her. That year, he met for the first time since childhood Lady Elizabeth Bowes-Lyon, the youngest daughter of the Earl and Countess of Strathmore and Kinghorne. He became determined to marry her. She rejected his proposal twice, in 1921 and 1922, reportedly because she was reluctant to make the sacrifices necessary to become a member of the royal family. In the words of Lady Elizabeth's mother, Albert would be "made or marred" by his choice of wife. After a protracted courtship, Elizabeth agreed to marry him.

Who was Albert infatuated with?
---
A: Sheila, Lady Loughborough

Problem: Fossilized spores suggest that higher plants (embryophytes) have lived on land for at least 475 million years. Early land plants reproduced sexually with flagellated, swimming sperm, like the green algae from which they evolved. An adaptation to terrestrialization was the development of upright meiosporangia for dispersal by spores to new habitats. This feature is lacking in the descendants of their nearest algal relatives, the Charophycean green algae. A later terrestrial adaptation took place with retention of the delicate, avascular sexual stage, the gametophyte, within the tissues of the vascular sporophyte. This occurred by spore germination within sporangia rather than spore release, as in non-seed plants. A current example of how this might have happened can be seen in the precocious spore germination in Selaginella, the spike-moss. The result for the ancestors of angiosperms was enclosing them in a case, the seed. The first seed bearing plants, like the ginkgo, and conifers (such as pines and firs), did not produce flowers. The pollen grains (males) of Ginkgo and cycads produce a pair of flagellated, mobile sperm cells that "swim" down the developing pollen tube to the female and her eggs.
What is the common name for Selaginella?

Answer: the spike-moss

The Battle of Worth (also known as Froschwiller or Reichshoffen) began when the two armies clashed again on 6 August near Worth in the town of Froschwiller, about 10 miles (16 km) from Wissembourg. The Crown Prince of Prussia's 3rd army had, on the quick reaction of his Chief of Staff General von Blumenthal, drawn reinforcements which brought its strength up to 140,000 troops. The French had been slowly reinforced and their force numbered only 35,000. Although badly outnumbered, the French defended their position just outside Froschwiller. By afternoon, the Germans had suffered c.10,500 killed or wounded and the French had lost a similar number of casualties and another c.9,200 men taken prisoner, a loss of about 50%. The Germans captured Froschwiller which sat on a hilltop in the centre of the French line. Having lost any hope for victory and facing a massacre, the French army disengaged and retreated in a westerly direction towards Bitche and Saverne, hoping to join French forces on the other side of the Vosges mountains. The German 3rd army did not pursue the French but remained in Alsace and moved slowly south, attacking and destroying the French garrisons in the vicinity.
What battle began when two armies collided in the town of Froschwiller?
A: The Battle of Worth

Context and question: In Mexico, Carnival is celebrated in about 225 cities and towns. The largest is in Mazatlan and the city of Veracruz with others in Baja California and Yucatan. The larger city Carnivals employ costumes, elected queens and parades with floats, but Carnival celebrations in smaller and rural areas vary widely depending on the level of European influence during Mexico's colonial period. The largest of these is in Huejotzingo, Puebla where most townspeople take part in mock combat with rifles shooting blanks, roughly based on the Battle of Puebla. Other important states with local traditions include Morelos, Oaxaca, Tlaxcala and Chiapas.
What is the mock combat roughly based on?
Answer: the Battle of Puebla

Question: The human brain is not fully developed by the time a person reaches puberty. Between the ages of 10 and 25, the brain undergoes changes that have important implications for behavior (see Cognitive development below). The brain reaches 90% of its adult size by the time a person is six years of age. Thus, the brain does not grow in size much during adolescence. However, the creases in the brain continue to become more complex until the late teens. The biggest changes in the folds of the brain during this time occur in the parts of the cortex that process cognitive and emotional information.
Is there an answer to this question: The brain reaches what percentage of its adult size by the time a person is six years old?

Answer: 90%

Problem: Bermuda:

Bermuda was discovered in 1503 by Spanish explorer Juan de Bermudez. It is mentioned in Legatio Babylonica, published in 1511 by historian Pedro Martir de Angleria, and was also included on Spanish charts of that year. Both Spanish and Portuguese ships used the islands as a replenishment spot to take on fresh meat and water. Legends arose of spirits and devils, now thought to have stemmed from the calls of raucous birds (most likely the Bermuda petrel, or Cahow) and the loud noise heard at night from wild hogs. Combined with the frequent storm-wracked conditions and the dangerous reefs, the archipelago became known as the Isle of Devils. Neither Spain nor Portugal tried to settle it.

When was Legatio Babylonica published by Pedro Angleria de Martir?
