1. The following lines of code are correct. If age >= 13 And < 20 Then txtOutput.Text = ";You are a teenager." End If 2. The Else part of an If block may be omitted if no action is associated with it. 3. Given that x = 7, y = 2, and z = 4, the following If block will display "TRUE". If (x >y) Or (y > z) Then txtBox.Text = "TRUE" End If 4. Given that x = 7, y = 2, and z = 4, the following If block will display "TRUE" If (x > y) And (y > z) Then txtBox.Text = "TRUE' End If 5. Every If block must have a Then and an Else.
This method uses the < and > operators to compare array subscripts, as when index is compared against the length of the array, a.length. The method also uses these operators to compare array elements against each other, for example, in an expression such as a[scan-1]>unSortedValue. What would happen if we change every < operator to >, and change every > operator to
Consider the following implementation of insertion sort: ``` public static void insertionSort(int [ ] array) { int unsortedValue; // The first unsorted value int scan; // Used to scan the array // The outer loop steps the index variable through // each subscript in the array, starting at 1. This // is because element 0 is considered already sorted. for (int index = 1; index < array.length; index++) { // The first element outside the sorted segment is // array[index]. Store the value of this element // in unsortedValue unsortedValue = array[index]; // Start scan at the subscript of the first element // outside the sorted segment. scan = index; // Move the first element outside the sorted segment // into its proper position within the sorted segment. while (scan > 0 && array[scan-1] > unsortedValue) { array[scan] = array[scan - 1]; scan --; } // Insert the unsorted value in its proper position // within the sorted segment. array[scan] = unsortedValue; } } ``` A) Instead of sorting in ascending order, the method would sort in descending order B) The method would throw an array index out of bounds exception C) The method would return, leaving the array unmodified D) The method would modify the array, but the array would likely not be sorted correctly

Give an example of a program at site A that requires the join of two tables, one at site B and one at site C. State the assumptions needed to justify the result that, as far as communication costs are concerned, the best implementation is to ship the table at site B to site C, do the join there, and then send the result to site A.
