Consider the following statements :
  1. 1.

    If f :S2 → ℝ2 is C1 then f-1 (y) is finite for “most“ points y ∈ ℝ.

  2. 2.

    Two lines in ℝ3 do not intersect “in general.“

  3. 3.

    If f: ℝ→ ℝ is C1, “almost all“ horizontal lines in ℝ × ℝ are nowhere tangent to the graph of f.

  4. 4.

    “Generically“ a C1 immersion S1 → ℝ2 has only a finite number of crossing points.
