Answer:
The claim is false and can be refuted
Explanation:
1) This claim is false, that there is summer when Earth is closest to the sun and winter when the Earth is farthest from the sun.
If it is so, than why seasons are Opposite in two hemispheres. It is summer in the Northern Hemisphere, when it is winter in the southern hemisphere. Alternatively it is Winter in the northern hemisphere, while it is summer in the southern hemisphere.
If the seasons occured due to the distance from, sun, then it should be same season in both the hemispheres, when Earth is farthest and closest from the Sun. Why are seasons different in both hemispheres. So this claim is false.
2) This claim is false, because actually Earth is closest to the Sun on January 3-4, when it is Winter in Northern Hemisphere and summer in Southern hemisphere. So why it is not Summer in both hemispheres, since the Earth is closest to the Sun.
Earth is farthest from the Sun on July 4, which is actually summer in Northern Hemisphere and winter in Southern hemisphere. So why is it not winter in both the hemispheres, since the Earth is Farthest from the Sun.
Hence based on these two arguments, the claim is false and can be refuted.
Answer:The people of the Middle East and North Africa (MENA) have long played an integral, if sometimes volatile, role in the history of human civilization. MENA is one of the cradles of civilization and of urban culture. Three of the world’s major religions originated in the region — Judaism, Christianity, and Islam. Universities existed in MENA long before they did in Europe. In modern times, MENA’s politics, religion, and economics have been inextricably tied in ways that affect the globe. The region’s vast petroleum supply — two-thirds of the world’s known oil reserves — is a major reason for the world’s interest. But the influence of MENA extends beyond its rich oil fields. It occupies a strategically important geographic position between Asia, Africa, and Europe. It has often been caught in a tug-of-war of land and influence that affects the entire world.
Today, MENA’s rapid population growth exacerbates the challenges that this region faces as it enters the third millennium. For hundreds of years, the population of MENA fluctuated around 30 million, reaching 60 million early in the 20th century. Only in the second half of 20th century did population growth in the region gain momentum. The total population increased from around 100 million in 1950 to around 380 million in 2000 — an addition of 280 million people in 50 years. During this period the population of the MENA region increased 3.7 times, more than any other major world region
