Week 1 Quiz: 1000 images with new species

I selected the correct answer first time, but it was graded as wrong. After that I tried two more test and checked other answers and they were all also graded as wrong. The comment said that the option with I first selected is correct. Please check the grade system.

The quiz grader is likely correct - otherwise we’d get a lot of comments about it (instead of just yours).

You have to read the questions very carefully, and each time you re-take a quiz, you may get a different combination of answers offered, and in a different order.
