Background Paragraph: During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seasonal lag, June, July, and August are the warmest months in the Northern Hemisphere while December, January, and February are the warmest months in the Southern Hemisphere. 
Story: Bill is planning some trips for his business and his family. His coworkers have informed him that they would like to travel in the summer months of June, July, and August, and prefer the temperature to be at its warmest. Bill is also planning to travel with his family and they would prefer to also go when it is the warmest part of the year, but can only travel in December, January, or February.  The options for travel are in the Chile which is in the Southern Hemisphere, and Arizona in the Northern Hemisphere.
Where should Bill take his coworkers to insure they are there in the warmest parts of the year? Where should Bill take his family to insure it is the warmest part of the year? Will Arizona be warmer or colder than Chile in August? Will Arizona be warmer or colder than Chile in December? Will Arizona be warmer or colder than Chile in February? Will Arizona be warmer or colder than Chile in January? Will Arizona be warmer or colder than Chile in July? Will Arizona be warmer or colder than Chile in June? Will Chile be warmer or colder than Arizona in August? Will Chile be warmer or colder than Arizona in June?
