Identify the sequence in which these words would be listed in an English dictionary.

1. Barrel
2. Beacon
3. Beauty
4. Beaker
5. Become

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

To arrange the given words in dictionary (alphabetical) order, we compare the letters of each word position by position from left to right.

Given words:
1. Barrel
2. Beacon
3. Beauty
4. Beaker
5. Become

Step 1: Compare the second letter of each word.
All five words start with the letter 'B'.
• Barrel has 'a' as its second letter.
• Beacon, Beauty, Beaker, and Become have 'e' as their second letter.
Since 'a' comes before 'e' in the English alphabet, Barrel (1) comes first.

Step 2: Compare the third letter of the remaining words (Beacon, Beauty, Beaker, Become).
• Beacon, Beauty, and Beaker have 'a' as their third letter.
• Become has 'c' as its third letter.
Since 'a' comes before 'c', Become (5) will come after Beacon, Beauty, and Beaker.

Step 3: Compare the fourth letter of Beacon, Beaker, and Beauty.
All three words share the prefix "Bea":
• Beacon has 'c' as its fourth letter.
• Beaker has 'k' as its fourth letter.
• Beauty has 'u' as its fourth letter.
Arranging 'c', 'k', and 'u' in alphabetical order gives:
'c' (Beacon) → 'k' (Beaker) → 'u' (Beauty)

Step 4: Determine the final sequence.
Combining all the steps in order:
1. Barrel (1)
2. Beacon (2)
3. Beaker (4)
4. Beauty (3)
5. Become (5)

Therefore, the words will be listed in the dictionary sequence 1, 2, 4, 3, 5.
