Another answer I don't fully understand.

If I join to affect/to induce with AND what about AND corrosion?

So is it more proper to say:

Something is enough to affect X and induce Y and Z
vs
Something is enough to affect X, induce Y and Z

i got this question qrong the first time too , because i misunderstood the sentence in the same way you have. the electric currents cause the blackouts AND the corrosion, i.e. the corrosion is a secondary cause of the aurora, not a direct one.

I think it can be written in two ways:

1. to affect...., to induce
2. to affect.....and induce

E follows the 2nd way.
