Difficulty: EasyAnalogy and Classification
In the following letter analogy, the second letter-group is related to the first letter-group following a specific positional shift rule in the English alphabet:
TRACK:USBDL::DRIVE:?\text{TRACK} : \text{USBDL} :: \text{DRIVE} : ?
Which of the following completes the given analogy?
  1. A
    CQHUD\text{CQHUD}
  2. ESJWF\text{ESJWF}Answer
  3. C
    ETKXG\text{ETKXG}
  4. D
    ESJVE\text{ESJVE}

Answer

The letter-group ESJWF\text{ESJWF} completes the analogy because each letter in DRIVE\text{DRIVE} is shifted forward by +1+1 position in the English alphabet.
In the initial term TRACK\text{TRACK}, each letter moves forward by 1 position in alphabetical order to form USBDL\text{USBDL} (T →\rightarrow U, R →\rightarrow S, A →\rightarrow B, C →\rightarrow D, K →\rightarrow L). Applying the exact same +1+1 forward shift to DRIVE\text{DRIVE} yields D →\rightarrow E, R →\rightarrow S, I →\rightarrow J, V →\rightarrow W, E →\rightarrow F, giving the result ESJWF\text{ESJWF}.

Step-by-Step Solution

1
Analyze the relationship between the first pair TRACK:USBDL\text{TRACK} : \text{USBDL}
T +1=+1 = U, R +1=+1 = S, A +1=+1 = B, C +1=+1 = D, K +1=+1 = L.
Identify the underlying transformation rule, which is a uniform forward shift of +1+1 for each letter.
2
Apply the identical +1+1 shift rule to the third term DRIVE\text{DRIVE}
D +1=+1 = E, R +1=+1 = S, I +1=+1 = J, V +1=+1 = W, E +1=+1 = F.
Determine the missing fourth term according to the established analogy rule.
