Refer to the following letter series and answer the question that follows. Counting to be done from left to right. (Left) S I C X Z O A K L N T E W A Q D F H G U K O (Right) How many such consonants are there, each of which is immediately preceded by a vowel and also immediately followed by a vowel?
None
Three
One
Two
Two
Scan for V-C-V patterns (Vowel-Consonant-Vowel) by focusing only on the vowels in the series: I, O, A, E, A, U, O.
Scan for V-C-V patterns (Vowel-Consonant-Vowel) by focusing only on the vowels in the series: I, O, A, E, A, U, O.
Identify Vowels and Consonants
The series is: S, I, C, X, Z, O, A, K, L, N, T, E, W, A, Q, D, F, H, G, U, K, O. Vowels present: I, O, A, E, A, U, O.
Scanning for V-C-V Triplets
We look for a consonant flanked by a vowel on both sides: 1) I-C-X (No), 2) Z-O-A (No), 3) O-A-K (No), 4) T-E-W (No), 5) A-Q-D (No), 6) G-U-K (No). Re-scanning: (1) Position 1-2-3: S, I, C (No). Position 2-3-4: I, C, X (No). Position 5-6-7: Z, O, A (No). Position 11-12-13: T, E, W (V-C-V is E-W-A). Let's check sequence carefully: S I C X Z O A K L N T E W A Q D F H G U K O. Vowel-Consonant-Vowel triplets: 1. (T) E (W) - No, wait: E is a vowel, W is a consonant, A is a vowel. This is (E, W, A). That is one. 2. (G) U (K) - No. 3. (U) K (O) - K is a consonant, U is a vowel, O is a vowel. Wait: U is a vowel, K is a consonant, O is a vowel. This is (U, K, O). That is two.
Verification of identified Triplets
Triplet 1: E (Vowel) W (Consonant) A (Vowel). Found at indices 12, 13, 14. Triplet 2: U (Vowel) K (Consonant) O (Vowel). Found at indices 20, 21, 22. Total count is two.
A: Zero is incorrect as two patterns exist. B: Three is incorrect because no third triplet matches the V-C-V criteria. C: One is incorrect as it misses the second V-C-V triplet.
D is correct because there are exactly two instances of the Vowel-Consonant-Vowel pattern: E-W-A and U-K-O.
When searching for patterns in long letter strings, always mark the vowels first. This significantly narrows down the search space for combinations like V-C-V or C-V-C.
