Solution

Let's analyze the given analogy: EYXJ : IGBR The relationship between the first and second letter-clusters seems to involve a shift of each letter by a certain number of positions in the alphabet: • E -> I (+3) • Y -> G (-5) • X -> B (-4) • J -> R (+9) Now let's apply the same logic to the fourth letter-cluster: CRFQ : GZJYZIQM • C -> G (+4) • R -> Z (+6) • F -> J (+6) • Q -> Y (+7) So, applying the same logic to the fifth letter-cluster: GZJYZIQM : ? • G -> ? • Z -> ? • J -> ? • Y -> ? • Z -> ? The shifts seem to be increasing by 2 each time. So, applying this logic: • G -> G + 2 = I • Z -> Z + 4 = D • J -> J + 6 = P • Y -> Y + 8 = G • Z -> Z + 10 = J Putting these together, we get the fifth letter-cluster as IGPDG, which matches option 3. DQUU. So, the answer is option 3. DQUU.
