Answer:
2. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.
Explanation:
The options are:
1. Before a volcano erupts, earthquake activity beneath the volcano decreases.2. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.3. When a volcano erupts, the amount of carbon dioxide and sulfur dioxide emitted decreases. 4.Scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir.
The answer is certainly 2. as seismometers are being used to find out the details of the earthquake activities which occur inside a volcano. And with this information, the volcanologists then predict the eruption of that particular volcano. Hence, the 2nd option does not have any factual errors, and all the others have factual errors.
C would be the correct answer to this question

Answer:
I think a is correct answer.
Answer:
This program is executed in Dev C++ using C++ as a programming language.
Explanation:
#include<iostream>
using namespace std;
int main()
{
int carModelNo;
cout<<"Enter Car Model Number ";
cin>>carModelNo;
EnterAgain:
if(carModelNo==1969)
{
cout<<"Few safety features.";
}
else if(carModelNo==1979)
{
cout<<"Probably has seat belts.";
}
else if(carModelNo==1999)
{
cout<<"Probably has antilock brakes.";
}
else if(carModelNo==2000)
{
cout<<"Probably has airbags.";
}
else
{
"Car Model Information Currently not Available";
cout<<"Please enter the car model such as 1969, 1979, 1999, or 2000 ";
cin>>carModelNo;
goto EnterAgain;
}
return 0;
}
