Exam 2 matrices Q2d

[some dude]

did anyone get this:
"the toatal number of  birds, frogs, and lizards killed by the insecticide" ??
because i remember there was a '0' as the first element for the second matrix so doesnt that mean that insects didnt get added up to the total? please if that makes sense it would be very helpful

Correct. The trick to the question was understanding its context.

The question said that the process of killing insects also accidentally kills frogs and lizards. So the aim was to calculate how many frogs and lizards are killed as a side-effect.

plus birds?

[some dude]

 that would mean that itute got it wrong, i believe itute said "Q2d total no. killed after spraying"
also for the question before where it asked what the 20 birds means i just said:
"the number of birds killed by the insecticide" is that right or did i need to make reference to the number "20". might be a silly questipn but any help would be much appreciated!!:)
