ASTRONOMY TERM 2 FINAL ADDITIONAL QUESTIONS ABOUT THE MOVIE THE ANDROMEDA STRAIN
Q: What is the name of the alien organism?
A: The Andromeda Strain.
Q: Where is the facility that studies the organism located?
A: Under ground in Nevada.
Q: Two individuals survived the initial outbreak of the organism. Describe them.
A: A baby and an elderly man.
Q: Why did these individuals survive?
A: Andromeda can only survive in the human body within a very narrow range of blood pH. The babies pH was too high (basic), the old man's pH was too low (acidic).
Q: The facility was equipped with a fail safe device to prevent the escape of the organism. What was this device?
A: A nuclear bomb.
Q: Why would this fail safe device not be effective at destroying the organism?
A: The organism eats radiation for breakfast.
Q: How did this crisis eventually end?
A: The organism mutated into a form non-lethal to Earth life forms.

Hello Earth
Kate Bush
Hello earth
Hello earth
With just one hand held up high
I can blot you out
Out of sight
Peek-a-boo,
Peek-a-boo, little earth
With just my heart and my mind
I can be driving
Driving home
And you asleep
On the seat
I get out of my car
Step into the night
And look up at the sky
And there's something bright
Traveling fast
Look at it go
Look at it go

And you asleep
On the seat
I get out of my car
Step into the night
And look up at the sky
And there's something bright
Traveling fast
Look at it go

The choral section, performed by the Richard Hickox Singers, is taken from a Georgian folk song called 'Zinzkaro' ('By The Spring'), which Kate heard performed by the Vocal Ensemble Gordela on the soundtrack of Werner Herzog's 1979 film Nosferatu The Vampyre. The lyric translates as:
'I was passing by the spring.
There I met a beautiful woman with a jug on her shoulder.
I spoke a word to her and she left, offended.
I was passing by the spring.'
