Question

completing statements about euler

in 1771, misfortune struck euler again, when a cataract in his left eye robbed him of his sight entirely. incredibly, this did not seem to slow him at all. in fact, during his remaining thirteen years, his publishing output accelerated. of the 886 books and articles he produced in his lifetime – on topics including mathematics, philosophy, mechanics, electricity, astronomy, optics, and music – half of them were completed after total blindness!

use the drop-down menus to complete the statements about euler’s life after he lost his sight.

after the cataract took euler’s sight, he drop - down.

about how many books and articles did euler complete after he lost his sight entirely? drop - down

Explanation:

For the first statement "After the cataract took Euler’s sight, he"

From the passage: "Incredibly, this did not seem to slow him at all. In fact, during his remaining thirteen years, his publishing output accelerated." So the appropriate completion would be something like "increased his publishing output" (assuming the drop - down has this or similar option related to accelerating/publishing more).

For the second question "About how many books and articles did Euler complete after he lost his sight entirely?"

We know from the passage that Euler produced 886 books and articles in his lifetime, and half of them were completed after total blindness.

Step 1: Identify the total number of works

The total number of books and articles Euler produced in his lifetime is 886.

Step 2: Calculate half of the total

To find half of 886, we use the formula $\frac{886}{2}$.
$\frac{886}{2}=443$

Answer:

For the first statement (drop - down): increased his publishing output (or relevant option from the drop - down).
For the second question: 443.
