I was disappointed with that.

6, five I was certain of plus one guess.

I liked number 2 - the answer can be deduced with high confidence with a little study.

8/10. Pay attention to context and subtle clues.

8, 9, & 10 got me. Enjoyed it. Really wish "Bill Barr" was an option for question #1.

:)

8/10 though I got lucky on a number of guesses. Only was sure on 1), 2) & 3) As always the ability to eliminate options really helps. For 10) I was even able to eliminate 3 answers leaving only one possible option.

The two I got wrong were 6) where I avoided the correct answer thinking it was too obvious and had to be a red herring and the fruit related question where I could have sworn two of those answers were not berries. Tricky...

8/10. I didn't correctly guess the microscope picture of the flower, and I got the moon distance wrong but I think the question was ambiguous. The answer given as correct (about 238,900 miles) is the mean distance from the Earth's center to the moon's center. I thought the question was looking for the distance between them, that is between the earth's surface and the moon's surface, which is about 5,000 miles less, so I went for the option nearest 234,000.

5 and I guessed one.
I did not get phosphorus! All that ADP and ATP!!! Annoyed.
Edit, of the 4 biology questions I got one right and that was a half guess!

yeah phosphorus was tricky since it breaks the trend of elemental abundances being relatively uncommon in the universe it is also being depeleted by humans so quickly that it is creating a looming crisis as the Earth's phosphorus is becoming washed out to sea or concentrated in cemeteries and landfills. Without the molecules built from it we can't take in energy from food or replicate genetic information. I wouldn't be surprised if gross missuse and waste of resources could play a role in the Fermi paradox....

That's as depressing as my mediocre score.

5/10 BUT I changed 3 first correct answers.

Moon distance 234,000 miles, learned as a child. Not expecting center-to-center.
Take a daily potassium supplement, so chose it over phosphorus.
I knew where Discovery was but when I went back to score answers, hit the NASA button instead.
Guessed flower first due to Fibonacci spirals but changed to 'iris of eye' due to 'hole' bottom left.

Got old Marie correct as she wore different clothing and, in another context, knew she was at Solvay conference. Chose Fleming correctly due to lab coat and the objects in his hands.

It's a quiz @mfb a bit of fun. Also 93 million miles has a ring to it.

For fun I would have expected furlongs.
