Question

Find the missing letters.
_ _aba_ _ba_ab

• A. abba
• B. abbab
• C. baabb
• D. bbaba

Answer 1

The Correct Option is B

To solve the problem of identifying the missing letters in the sequence "_ _aba_ _ba_ab", let's break it down systematically:

1. Identify the given pattern: "_ _aba_ _ba_ab".
2. Look for a repeating sequence or pattern within the string. The identified part "aba" suggests that the other sections might follow a similar arrangement.
3. Note the position of "aba" in the sequence, which is another hint for a potential repetition.
4. Now, evaluate the options provided to find a sequence that, when inserted into blanks, completes the pattern:
   • Option 1: "abba" - if we fill the blanks, it results in "abbaabaabbaab" which does not fit the blanks as required.
   • Option 2: "abbab" - if placed in the blanks, the sequence becomes "abbababaab" which maintains the repeating structure of "aba", as "abb aba bab aba b".
   • Option 3: "baabb" - filling results in "baabbabaabbab" which does not give a discernible repeating pattern considering the location of "aba".
   • Option 4: "bbaba" - results in "bbabaababbaba" which mixes the pattern and the distinct sequence is not perceivable.
5. Conclude that option 2, "abbab", matches the pattern best.

Therefore, the missing letters that fit the given pattern logically and consistently are abbab.
