Question: In 2013, the northern atolls of the Marshall Islands experienced drought. The drought left 6,000 people surviving on less than 1 litre (0.22 imp gal; 0.26 US gal) of water per day. This resulted in the failure of food crops and the spread of diseases such as diarrhea, pink eye, and influenza. These emergencies resulted in the United States President declaring an emergency in the islands. This declaration activated support from US government agencies under the Republic's "free association" status with the United States, which provides humanitarian and other vital support.
Is there an answer to this question: What part of the Marshall Islands experienced drought in 2013?

Answer: the northern atolls


Question: The development of a three-field rotation system for planting crops[AA] increased the usage of land from one half in use each year under the old two-field system to two-thirds under the new system, with a consequent increase in production. The development of the heavy plough allowed heavier soils to be farmed more efficiently, aided by the spread of the horse collar, which led to the use of draught horses in place of oxen. Horses are faster than oxen and require less pasture, factors that aided the implementation of the three-field system.
Is there an answer to this question: What fraction of land was under cultivate using the three-field system?

Answer: two-thirds


Question: Post-European-contact Chamorro culture is a combination of American, Spanish, Filipino, other Micronesian Islander and Mexican traditions, with few remaining indigenous pre-Hispanic customs. These influences are manifested in the local language, music, dance, sea navigation, cuisine, fishing, games (such as batu, chonka, estuleks, and bayogu), songs and fashion. During Spanish colonial rule (1668–1898) the majority of the population was converted to Roman Catholicism and religious festivities such as Easter and Christmas became widespread. Post-contact Chamorro cuisine is largely based on corn, and includes tortillas, tamales, atole and chilaquiles, which are a clear influence from Spanish trade between Mesoamerica and Asia. The modern Chamorro language is a Malayo-Polynesian language with much Spanish and Filipino influence. Many Chamorros also have Spanish surnames because of their conversion to Roman Catholic Christianity and the adoption of names from the Catálogo alfabético de apellidos, a phenomenon also common to the Philippines.
Is there an answer to this question: In what year was the catalogo alfabetico de apellidos published?

Answer:
unanswerable
