//pop removes the last element, which would be disagree in the strings array
strings.pop()
//shift removes the first element, which would be 1 in the numbers array
numbers.shift()
//push adds an element(s) to the end of an array, booleans would now have 6 elements
booleans.push(true, false)
//An index position is the number that corresponds to an element in an array. Counting elements in an array starts at 0. The second element in the "strings" array is "Agree"
