supporting the theory of global forest fires ignited by a meteorite impact that
supporting the theory that global forest fires ignited by a meteorite impact✔️
that supports the theory of global forest fires that were ignited by a meteorite impact and that
in support of the theory that global forest fires were ignited by a meteorite impact and that

Correct Answer Logic:

It clearly expresses the theory: global forest fires ignited by a meteorite impact contributed to the extinction. In option A, the pronoun 'that' ambiguously modifies either 'meteorite impact' or 'fires.' Options C and D add unnecessary 'and that,' creating grammatical awkwardness. Option E changes the meaning by implying the meteorite directly caused the extinction rather than the forest fires.

Mechanical Engineering QUESTION #2413

Question 14

For a floating or submerged body, stability requires that the metacentric height $GM$ satisfies:

$GM < 0$ (overturning moment)
$GM > 0$ (righting moment — metacenter M above center of gravity G)✔️
$GM = 0$ (neutral stability only)
$GM$ must equal the center of buoyancy height

Correct Answer Logic:

Stability: metacentric height $GM=KB+BM-KG>0$ for stable equilibrium. When $GM>0$, any heel generates a righting moment restoring the body to upright.

Mathematics QUESTION #965

Question 15

Let a line pass through two distinct points $P(-2,-1,3)$ and $Q$, and be parallel to the vector $3\hat{i}+2\hat{j}+2\hat{k}$. If the distance of the point $Q$ from the point $R(1,3,3)$ is 5, then the square of the area of $\triangle PQR$ is equal to:

148
136
144
140✔️

Correct Answer Logic:

The line through $P$ parallel to $\vec{v}=3\hat{i}+2\hat{j}+2\hat{k}$ gives $Q = P + t\vec{v}$. Using $|QR|=5$ to find $t$, then computing $\text{Area}^2 = \frac{1}{2}|\vec{PQ}\times\vec{PR}|^2$ yields 140.

Question 18

A proposal has been made to trim the horns from rhinoceroses to discourage poachers; the question is _____ rhinoceroses after their horns are trimmed.

whether tourists will continue to visit game parks and see rhinoceroses after their horns are
whether tourists will continue to visit game parks to see one once their horns are
whether tourists will continue to visit game parks to see rhinoceroses once the animals' horns have been✔️
if tourists will continue to visit game parks and see rhinoceroses once the animals' horns are

Correct Answer Logic:

Whether' (not 'if') is proper in indirect questions. 'The animals' horns' eliminates the ambiguous pronoun 'their' (whose horns — tourists' or rhinoceroses'?). 'To see rhinoceroses' (infinitive of purpose) is more precise than 'and see.' Options D and E incorrectly use 'if.' Options A and B retain ambiguous 'their.'
