7. Use the information below to answer the question that follows.

Problem:

A box holds a lot of red marbles and blue marbles. Select a marble from the box and place it on the table. Continue selecting marbles from the box until you have selected 3 red marbles or 5 total marbles, whichever comes first.

Student work:

red = 0
total = 0

while (total  less than or equal to  5)
marble = select_from(marbles)
total = total + 1

if (marble.color  equals equals  "red")
red = red + 1

if (red  equals equals  3)
break  hashtag  exit loop

A student created the algorithm shown to solve the given problem. The student's solution contains one or more errors. Which of the following algorithms corrects the error(s)?

  1. red = 0
    total = 0

    marble = select_from(marbles)

    while (total  less than  5)
    total = total + 1

    if (marble.color  equals equals  "red")
    red = red + 1

    if (red  equals equals  3)
    break  hashtag  exit loop

  2. red = 0
    total = 0

    while (total  less than  5)
    marble = select_from(marbles)
    total = total + 1

    if (marble.color  equals equals  "red")
    red = red + 1

    if (red  equals equals  3)
    break  hashtag  exit loop

  3. red = 0
    total = 0

    marble = select_from(marbles)

    while (total  equals equals  5)
    total = total + 1

    if (marble.color  equals equals  "red")
    red = red + 1

    if (red  equals equals  3)
    break  hashtag  exit loop

  4. red = 0
    total = 0

    while (total  equals equals  5)
    marble = select_from(marbles)
    total = total + 1

    if (marble.color  equals equals  "red")
    red = red + 1

    if (red  equals equals  3)
    break  hashtag  exit loop
