Input: Adolescence
Puberty occurs through a long process and begins with a surge in hormone production, which in turn causes a number of physical changes. It is the stage of life characterized by the appearance and development of secondary sex characteristics (for example, a deeper voice and larger adam's apple in boys, and development of breasts and more curved and prominent hips in girls) and a strong shift in hormonal balance towards an adult state. This is triggered by the pituitary gland, which secretes a surge of hormonal agents into the blood stream, initiating a chain reaction to occur. The male and female gonads are subsequently activated, which puts them into a state of rapid growth and development; the triggered gonads now commence the mass production of the necessary chemicals. The testes primarily release testosterone, and the ovaries predominantly dispense estrogen. The production of these hormones increases gradually until sexual maturation is met. Some boys may develop gynecomastia due to an imbalance of sex hormones, tissue responsiveness or obesity.

Puberty causes what to happen in boys?
Output: a deeper voice and larger adam's apple

Input: Architecture

Output: China

Input: Paris
Clovis the Frank, the first king of the Merovingian dynasty, made the city his capital from 508. A gradual immigration by the Franks also occurred in Paris in the beginning of the Frankish domination of Gaul which created the Parisian Francien dialects. Fortification of the Île-de-France failed to prevent sacking by Vikings in 845 but Paris' strategic importance—with its bridges preventing ships from passing—was established by successful defence in the Siege of Paris (885–86). In 987 Hugh Capet, Count of Paris (comte de Paris), Duke of the Franks (duc des Francs) was elected King of the Franks (roi des Franks). Under the rule of the Capetian kings, Paris gradually became the largest and most prosperous city in France.

who was the first king of the Merovingian dynasty?
Output: Clovis the Frank

Input: Hydrogen
Hydrogen poses a number of hazards to human safety, from potential detonations and fires when mixed with air to being an asphyxiant in its pure, oxygen-free form. In addition, liquid hydrogen is a cryogen and presents dangers (such as frostbite) associated with very cold liquids. Hydrogen dissolves in many metals, and, in addition to leaking out, may have adverse effects on them, such as hydrogen embrittlement, leading to cracks and explosions. Hydrogen gas leaking into external air may spontaneously ignite. Moreover, hydrogen fire, while being extremely hot, is almost invisible, and thus can lead to accidental burns.

What can hydrogen embrittlement lead to?
Output:
cracks and explosions
