Problem: Vacuum:

Rapid decompression can be much more dangerous than vacuum exposure itself. Even if the victim does not hold his or her breath, venting through the windpipe may be too slow to prevent the fatal rupture of the delicate alveoli of the lungs. Eardrums and sinuses may be ruptured by rapid decompression, soft tissues may bruise and seep blood, and the stress of shock will accelerate oxygen consumption leading to hypoxia. Injuries caused by rapid decompression are called barotrauma. A pressure drop of 13 kPa (100 Torr), which produces no symptoms if it is gradual, may be fatal if it occurs suddenly.

What causes barotrauma?

A: rapid decompression

Problem: Galicia is further divided into 53 comarcas, 315 municipalities (93 in A Coruna, 67 in Lugo, 92 in Ourense, 62 in Pontevedra) and 3,778 parishes. Municipalities are divided into parishes, which may be further divided into aldeas ("hamlets") or lugares ("places"). This traditional breakdown into such small areas is unusual when compared to the rest of Spain. Roughly half of the named population entities of Spain are in Galicia, which occupies only 5.8 percent of the country's area. It is estimated that Galicia has over a million named places, over 40,000 of them being communities.
How many comarcas does Galicia consist of?

Answer: 53

Context and question: Since the latewood of a growth ring is usually darker in color than the earlywood, this fact may be used in judging the density, and therefore the hardness and strength of the material. This is particularly the case with coniferous woods. In ring-porous woods the vessels of the early wood not infrequently appear on a finished surface as darker than the denser latewood, though on cross sections of heartwood the reverse is commonly true. Except in the manner just stated the color of wood is no indication of strength.
With the exception of earlywood/latewood difference in some types of trees, how much of an indication of strength is a wood's color?
Answer: no indication

Question: Some breeds of dogs are prone to certain genetic ailments such as elbow and hip dysplasia, blindness, deafness, pulmonic stenosis, cleft palate, and trick knees.
