Question 1237 in the bank

What is the meaning of this sign?

A red-bordered white triangle with a black shape sloping down from left to right, above a white plate showing 2500. Meaning: Steep downhill slope about 2,500 meters ahead.
  1. Correct answer: Steep downhill slope about 2,500 meters ahead.
  2. In 2,500 meters a steep uphill climb begins.
  3. Steep downhill slope for 2,500 meters begins here.
  4. The end of a 2,500-meters downhill slope section.

Why this is the answer

The correct answer in the official bank: Steep downhill slope about 2,500 meters ahead.

The sign warns of a steep downhill slope, and the number on the plate beneath it shows the distance to its start. So the slope begins about 2,500 meters ahead of you, not at the sign itself. The number is not the length of the slope, and it is not a distance to an uphill climb.
