Answer:
Option B; 30 SECONDS OR LESS.
Explanation:
Short-term memory, also known as primary or active memory, is the information we are currently aware of or thinking about. 
When short-term memories are not rehearsed or actively maintained, they last mere seconds.
Most of the information kept in short-term memory will be stored for less than 30 seconds (approximately 20 to 30 seconds), but it can be just seconds if rehearsal or active maintenance of the information is not done.
Therefore, Anita likely will be able to retain the information in short-term memory, without additional processing, for 30 SECONDS OR LESS.
 
        
             
        
        
        
Answer:
// program in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main() 
{
// variable
int inp_month;
cout<<"Enter month:";
// read month
cin>>inp_month;
// if month is february 
if(inp_month==2)
cout<<"Number of days in month:28"<<endl;
// if month is 4 or 6 or 9 or 11
else if(inp_month==4||inp_month==6||inp_month==9||inp_month==11)
cout<<"Number of days in month:30"<<endl;
else
// for others month
cout<<"Number of days in month:31"<<endl;
return 0;
}
Explanation:
Read month from user and assign it to variable "inp_month".If month is 2 then  there is 28 days in the month.If input month is 4 or 6 or 9 or 11 then there is 30 days in the month.For other month there will be 31 days in month.We assume there is no leap year.
Output:
Enter month:4                                                                                                              
Number of days in month:30
