Select the option that represents the correct alphabetical sequence of the given words as they appear in a standard dictionary:

1. Beacon 2. Beauty 3. Beach 4. Bear 5. Beast

The correct answer is 3, 4, 1, 2, 5.

To determine the correct alphabetical sequence of the words as they appear in a standard dictionary, we compare the letters of each word position by position from left to right:
1. Beacon
2. Beauty
3. Beach
4. Bear
5. Beast

Step 1: Identify common starting letters
All five words begin with the same initial three-letter prefix, "Bea-". Therefore, their ordering is determined by looking at the fourth letter of each word.

Step 2: Compare the fourth letters
• Word 3 (Beach): 4th letter is c
• Word 4 (Bear): 4th letter is r
• Word 1 (Beacon): 4th letter is c
• Word 2 (Beauty): 4th letter is u
• Word 5 (Beast): 4th letter is s

Step 3: Arrange the words in order
• 3. Beach takes the first position.
• 4. Bear follows next.
• 1. Beacon comes third in sequence.
• 2. Beauty is placed fourth.
• 5. Beast comes last.

Thus, arranging the word numbers according to this sequence gives: 3, 4, 1, 2, 5.
