Africa
Explanation:
Africa by land area, is the second largest continent.
It covers a land area of about 11,608,000 square miles. <em>This is next to Asia in land area, which covers a land area of 17,212,000 square miles.</em>
Based on historical and archaeological evidence, humans have lived in Africa for more than 5 million years. This earned Africa the name "Mother Continent".
The first hominins <em>(primates which can be considered as directly ancestral to humans )</em> in Africa emerged about 6-7 million years ago, and among the earliest anatomically modern human skulls found so far were discovered at Ethiopia

Answer A.
Answer: 30 year
Explanation:
The normal high temperature for a given day determined by the temperature of a place averaged over a period of time, often 30 years. This is also described as climate information. Climate information includes the statistical weather information that tells us about the normal weather, and also the range of weather extremes for a location. Most weather forecasters rely of past weather to predict the normal high temperature of a given day.
The average high or low temperature is the normalized high or low temperature for at least a 30 year period. Therefore, an average high is a statistical average. Records need to be kept at least 30 years for an average high temperature, for the information to be statistically meaningful.
