Claim: the school should only purchase and drive electric
vehicles to the united states decrease its dependence
on foreign oil.
which statement is an example of a major counterclaim to address in an
argumentative research essay with this claim?
o
a. electric vehicles are dangerous, and people are at risk of getting
electrocuted when driving them.
b. having people switch over from regular cars to electric vehicles is
just a conspiracy to get them to use alternate means of
transportation.
c. converting to electric vehicles would be too costly for schools
that are already facing severe budget problems.
o
d. electric vehicles are so ugly that high school students would be
embarrassed to be seen in them.

Converting to electric vehicles would be too costly for schools that are already facing severe budget problems.

Step-by-step explanation:

It is directly addressing the given claim.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
