Link: Telescopes

Passage: "Humans have been making and using lenses for magnification for thousands and thousands of years. However, the first true telescopes were made in Europe in the late 16th century. These telescopes used a combination of two lenses to make distant objects appear both nearer and larger."

Question: How long have humans been magnifying objects using lenses?

Choices:

1. For a thousand years
2. Since the late 16th century
3. For thousands of years
4. Since the early 16th century

Correct answer in dataset: 2

Actually correct answer?

Telescope is a two lens system and humans, indeed, have been magnifying objects using telescopes since the late 16th century. However, the question is about magnification in general and it is possible to magnify an object using a single lens and this, according to the passage, has been done for thousands of years. So shouldn't the correct answer be 3?
