Correct answer: E
Concept
This is a word-machine that rewrites every word of the phrase through a fixed chain of steps. Each step applies ONE deterministic rule to all words simultaneously, keeping the words in their original left-to-right order. To answer, you reconstruct the same four rules from the worked examples and apply them to the new phrase.
The four rules, read off the example table, are:
Step I (letter swap): swap the first and last letter of each word (e.g. lost → tosl).
Step II (length code): for an EVEN-length word take its two middle letters and append (length + 1); for an ODD-length word take (last + first letter) and append (length − 1). e.g. lost (4, even) → os5; all (3, odd) → la2. Both letters always come from the ORIGINAL word — not from Step I's swapped output; only Step III chains from Step II's own code.
Step III (shift + symbol): shift each of the two letters — a vowel moves +1, a consonant moves −1 — and append # if the Step-II digit is odd or @ if it is even. e.g. os5 → pr#.
Step IV (pairing): group the four Step-III codes by symbol. For the two # codes join their LAST letters; for the two @ codes join their FIRST letters. The group whose code appears FIRST in word order is written first.
Application to “recover that device issue”
Process all four words through every step:
Word | Step I | Step II | Step III |
|---|---|---|---|
recover (7, odd) | recover | rr6 | qq@ |
that (4, even) | that | ha5 | gb# |
device (6, even) | eevicd | vi7 | uj# |
issue (5, odd) | essui | ei4 | fj@ |
Now build Step IV. The Step-III codes are qq@, gb#, uj#, fj@.
The two @ codes are qq and fj → join their first letters → qf@.
The two # codes are gb and uj → join their last letters → bj#.
Ordering: the first word recover carries the @ symbol, so the @ pair is written first. Therefore Step IV = qf@ bj#.
Cross-check
The example order statue received again begins with order → qp@, and its Step IV in the table is qm@ sj# — the @ pair first. Our phrase also begins with an @ word, confirming qf@ must precede bj#.
Comparing qf@ bj# against the five choices: one choice has the right pair but in reversed order, another has the right letters but the wrong symbols, and the rest differ in letters. No choice reproduces qf@ bj# exactly, so the matching answer is None of these.
