Irritable as in "capable of responding to a stimuli."

I was confused by these two statements given in a book about viruses-

1- "They lack irritability."
2- "They show irritability and respond to environmental conditions such as heat, UV rays, humidity, drought, alcohol etc."

Can the meaning of the word "irritability" be contextually different in the above cases?

Or Is the book just plain stupid? ;)

Please explain to me whether the statement below are true or false:
1. If F(x) is an antiderivative of f(x), then y = F(x) is a solution to the
differential equation dy/dx = f(x).
2. If y =F(x) is a solution to the differential equation dy/dx = f(x),
then F(x) is an antiderivative of f(x)
3. If an object has constant nonzero acceleration, then the position
of the object as a function of time is a quadratic polynomial.

Thanks for all the help!

Betelgeuse (Alpha Orionis) is a red super giant about 430 LY away, with about 15 the mass of Sol.

I am writing a story and need to know some likely facts:

Assume it went supernova 430 years ago and created a black hole. What effects would be felt at Earth when the light/energy reached us, what would the build-up look like, how long would the night sky be lit by it, what effect would such a large BH have at this range? Etc.
