Tucson has a desert climate (Köppen BWh), with two major seasons, summer and winter; plus three minor seasons: fall, spring, and the monsoon. Tucson averages 11.8 inches (299.7 mm) of precipitation per year, more than most other locations with desert climates, but it still qualifies due to its high evapotranspiration; in other words, it experiences a high net loss of water. A similar scenario is seen in Alice Springs, Australia, which averages 11 inches (279.4 mm) a year, but has a desert climate.

What is the average amount of  yearly precipitation in Tuscon in inches?
Answer: 11.8

Over a dozen racial categories would be recognized in conformity with all the possible combinations of hair color, hair texture, eye color, and skin color. These types grade into each other like the colors of the spectrum, and not one category stands significantly isolated from the rest. That is, race referred preferentially to appearance, not heredity, and appearance is a poor indication of ancestry, because only a few genes are responsible for someone's skin color and traits: a person who is considered white may have more African ancestry than a person who is considered black, and the reverse can be also true about European ancestry. The complexity of racial classifications in Brazil reflects the extent of miscegenation in Brazilian society, a society that remains highly, but not strictly, stratified along color lines. These socioeconomic factors are also significant to the limits of racial lines, because a minority of pardos, or brown people, are likely to start declaring themselves white or black if socially upward, and being seen as relatively "whiter" as their perceived social status increases (much as in other regions of Latin America).

Where is there a lot of complexity in racial classifications?
Answer: Brazil

Reform of the liturgy had been a part of the liturgical movements in the 20th century mainly in France, and Germany which were officially recognized by Pius XII in his encyclical Mediator Dei. During the pontificate of Pius XII, the Vatican eased regulations on the use of Latin in Roman Catholic liturgies, permitting some use of vernacular languages during baptisms, funerals and other events. In 1951 and 1955, the Easter liturgies underwent revision, most notably including the reintroduction of the Easter Triduum. The Second Vatican Council made no changes to the Roman Missal, but in the document Sacrosanctum Concilium mandated that a general revision of it take place. After the Vatican Council, in April 1969, Paul VI approved the "new Order of Mass" promulgated in 1970, as stated in the Acta Apostolica Sedis to "end experimentation" with the Mass and which included the introduction of three new Eucharistic Prayers to what was up to then a single Roman Canon.

How many new prayers were included in the official mass reforms of 1969?
Answer:
three
