The South Saharan steppe and woodlands ecoregion is a narrow band running east and west between the hyper-arid Sahara and the Sahel savannas to the south. Movements of the equatorial Intertropical Convergence Zone (ITCZ) bring summer rains during July and August which average 100 to 200 mm (3.9 to 7.9 in) but vary greatly from year to year. These rains sustain summer pastures of grasses and herbs, with dry woodlands and shrublands along seasonal watercourses. This ecoregion covers 1,101,700 km2 (425,400 mi2) in Algeria, Chad, Mali, Mauritania, and Sudan.

What months do the summer rains happen?
Answer: July and August

Another solution to the problem of causality-based temporal paradoxes is that such paradoxes cannot arise simply because they have not arisen. As illustrated in numerous works of fiction, free will either ceases to exist in the past or the outcomes of such decisions are predetermined. As such, it would not be possible to enact the grandfather paradox because it is a historical fact that your grandfather was not killed before his child (your parent) was conceived. This view doesn't simply hold that history is an unchangeable constant, but that any change made by a hypothetical future time traveler would already have happened in his or her past, resulting in the reality that the traveler moves from. More elaboration on this view can be found in the Novikov self-consistency principle.

What paradox cannot be enacted because it is a fact that your grandfather was not killed before your parent was conceived?
Answer: the grandfather paradox

In May 2015, a coalition of more than 60 Asian-American organizations filed federal complaints with the Education and Justice Departments against Harvard University. The coalition asked for a civil rights investigation into what they described as Harvard's discriminatory admission practices against Asian-American applicants. The complaint asserts that recent studies indicate that Harvard has engaged in systematic and continuous discrimination against Asian Americans in its "holistic" admissions process. Asian-American applicants with near-perfect test scores, top-one-percent grade point averages, academic awards, and leadership positions are allegedly rejected by Harvard because the university uses racial stereotypes, racially differentiated standards, and de facto racial quotas. This federal complaint was dismissed in July 2015 because the Students for Fair Admissions lawsuit makes similar allegations.

What grade average do some students have that are being rejected?
Answer:
top-one-percent grade point averages
