Question 1: Let X be a subset of R. What does it mean for x to be an adherent point of X?

	For every epsilon > 0, there exists a y in X such that \|y-x\| < epsilon.
	For every epsilon > 0, there exists a y in X such that 0 < \|y-x\| < epsilon.
	There exists epsilon > 0 and y in X such that 0 < \|y-x\| < epsilon.
	For every epsilon > 0 and all y in X, we have \|y-x\| < epsilon.
	For every y in X, there exists epsilon > 0 such that \|y-x\| < epsilon.
	There exists epsilon > 0 such that 0 < \|y-x\| < epsilon for all y in X.
	There exists y in X such that \|y-x\| < epsilon for all epsilon > 0.

	For every epsilon > 0, there exists a y in X such that \|y-x\| < epsilon.
	For every epsilon > 0, there exists a y in X such that 0 < \|y-x\| < epsilon.
	There exists epsilon > 0 and y in X such that 0 < \|y-x\| < epsilon.
	For every epsilon > 0 and all y in X, we have \|y-x\| < epsilon.
	For every y in X, there exists epsilon > 0 such that \|y-x\| < epsilon.
	There exists epsilon > 0 such that 0 < \|y-x\| < epsilon for all y in X.
	There exists y in X such that \|y-x\| < epsilon for all epsilon > 0.
