PROBLEM: Red blood cells (RBCs), also called erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O) to the body tissues -- via blood flow through the circulatory system. RBCs take up oxygen in the lungs, or gills of fish, and release it into tissues while squeezing through the body's capillaries.

PROBLEM: The Olympic Winter Games (official name) (French: Jeux olympiques d'hiver) is a major international sporting event held once every four years, for sports practised on snow and ice. The first Winter Olympics, the 1924 Winter Olympics, was held in Chamonix, France. The original five sports (broken into nine disciplines) were bobsleigh, curling, ice hockey, Nordic skiing (consisting of the disciplines military patrol, cross-country skiing, Nordic combined, and ski jumping), and skating (consisting of the disciplines figure skating and speed skating). The Games were held every four years from 1924 to 1936, interrupted in 1940 and 1944 by World War II, and resumed in 1948. Until 1992 the Winter and Summer Olympic Games were held in the same years, but in accordance with a 1986 decision by the International Olympic Committee (IOC) to place the Summer and Winter Games on separate four-year cycles in alternating even-numbered years, the next Winter Olympics after 1992 was in 1994.

SOLUTION: when did the olympics switch to every 2 years
