When comparing the catastrophic eruption in Sumatra 71,000 years ago and the 1991 eruption of Mt. Pinatubo, we find that "both eruptions caused a drop in the average temperatures across the Earth".
What is catastrophic eruption in Sumatra and in Mt. Pinatubo?The most recent Toba eruption was a supervolcano eruption that took place at the location of the present-day Lake Toba in Sumatra, Indonesia, some 71,000 years ago.
Reason for Toba eruption is-
The greatest known volcanic explosion on Earth in the last two million years, the Toba volcano eruption, produced a steep-walled crater that eventually became the source of the ancient lake. Supervolcanic eruptions are exceedingly unusual and massive eruptions like this one.On June 15, 1991, Mount Pinatubo in the Philippines saw the second-biggest volcanic explosion of this century and by far the largest eruption to affect a highly populated area. The eruption caused massive mudflows, high-speed avalanches of hot ash and gas, and a hundreds-mile-wide cloud of volcanic ash.
Reason for Mount Pinatubo eruption is-
More than 32 km (20 mi) of magma beneath Mount Pinatubo was surging toward the surface, causing tiny volcano tectonic earthquakes and massive steam explosions that blew three holes in the volcano's north slope.To know more about supervolcano eruption, here

The function that is graphed in the image is f(x) = -4log(-x + 4).
What is deduced from the graph?
We can see that x-intercept is (3,0), when x=3, y=0, then, we use eliminate those of the 4 possible answers that could not be correct.
Note
log (1) = 0.
First answer:
log(x + 4). Why? Because when x=3,
log(x + 4)=log(3 + 4)= log 7, which is NOT zero.
Second answer It is not Zero
Third answer
log(x + 4). If x=3, we get log(7), which is not zero.
Fourth answer
f(x) = -4log(-x + 4). When x=3, we get f(3)= -4log(-x + 4)
= -4(log[1]) = 0.
Therefore, the Option D is correct.

If the amount of low, thick stratus cloud cover increases, Earth's climates would likely ________ due to increased ________.
If the amount of low, thick stratus cloud cover increases, Earth's climates would likely cool due to increased reflectivity.
What are stratus clouds?Low-level cloud layers which have very uniform grey or white coloring are known as stratus clouds. They can last for a very long time in their "nebulosus" state, which is frequently the scene of gloomy, overcast days. They are the lowest-lying type of cloud and can occasionally be seen at the surface as mist or fog.
When light winds lift cool, moist air over colder land or ocean surfaces, stratus clouds form under calm, stable conditions. These clouds can come in a range of densities and are occasionally opaque enough to darken the day and let little light through.
