Aedes aegypti, also known as the Yellow Fever Mosquito
Aedes albopictus, also known as the Asian Tiger Mosquito
No one got this one, but some guessed Anopheles. A good guess, but it's
the vector for malaria, which is not a virus. Aedes is the genus you
want for viruses.

Planet Nine -- any form of the number nine was marked correct. Planet X,
though, was wrong. That was what Percival Lowell named his undiscovered
planet, with the X standing for unknown, not a Roman numeral.

10. The range was 10 to 20 Earth masses

Neptune.
Pluto was at one time considered to have been predicted on this basis,
but later analysis showed that the effects the predictions were based on
were due to incorrect measurements. Another object predicted was Vulcan,
a hypothetical planet closer to the Sun than Mercury. It turns out that
the effect used to predict it was actually due to General Relativity.
Ceres (or the asteroid belt) was also predicted, but that was based on
numerology.

The one in Washington is in the Hanford Reservation, which you may
remember is the site where they made plutonium for nuclear weapons. The
Reservation is actually much larger than the area needed for the
reactors, but it had a very large buffer around it. LIGO is in that
buffer area.
