Volatile Facts: Keying General Knowledge for a Paper That Will Be Reused
You are setting the twenty-item General Knowledge and Current Affairs section of a practice paper for a batch that will use it from April to December. Two inherited items worry you. Item 9 reads: 'The present Chief Justice of India is ___,' with four names, keyed to the person in office on the date the pool was originally written. Item 14 reads: 'Telangana has how many districts?' keyed to 31 from a departmental PDF dated several years ago; the state government's own district portal, which you check on the day of setting, gives a different figure and carries a 'last updated' note two years later than the PDF. Your source policy permits only government portals, the Election Commission and the Press Information Bureau, and forbids coaching material as a keying source. The institute reuses practice papers across batches without revision, and the file goes to typesetting in four hours.
1. Apply a volatility test to both items. Which one is unsafe by construction, and which is unsafe because of a sourcing failure?

The two failures are different in kind and need different remedies.
Item 9 - volatile by construction. The key is not a fact about a subject; it is a fact about who currently occupies a post. Nothing in the syllabus content changes when the office changes hands, so the item's key can expire without any change in what candidates are expected to know. Such an item has zero shelf life and is unverifiable against an undated pool. It fails the reuse test outright, because the paper is reissued without revision.
Item 14 - stable in principle, unsafe through sourcing. The number of districts is a matter of administrative record; the concept being tested (that states are divided into districts, and that Telangana's map was reorganised) does not expire. The problem is that two official sources disagree and one is undated relative to the other. When official sources conflict, the item cannot be keyed with confidence, and guessing which figure the examiner will accept is not a defensible method.
A workable test for any item in a reusable paper: would the key change without any change in what the candidate is supposed to have learned? If yes, the item is volatile and must be date-stamped or converted.
2. Rewrite both items so that they are safe for a paper that will be reused. Give the rewritten stems and keys.

The principle is to shift from the changing instance to the stable structure that the item was really trying to test.
Item 9 - rewritten as a stable constitutional item:
The Chief Justice of India is appointed by the - (A) President of India (B) Prime Minister (C) Collegium of the Supreme Court (D) Union Law Minister
Key: (A). This tests the same topic area (the apex judiciary) through the constitutional provision - the Supreme Court is established under Article 124, and appointment is by the President - and it cannot expire.
Item 14 - rewritten as a stable reorganisation item:
Telangana was carved out of Andhra Pradesh by which legislation? (A) Andhra Pradesh Reorganisation Act, 2014 (B) States Reorganisation Act, 1956 (C) Telangana Formation Ordinance, 2013 (D) Union Territories Act, 1963
Key: (A). The state's formation by the 2014 Reorganisation Act is a fixed fact of record and does not need re-verification.
If a current-affairs item must be retained, the only defensible form is a date-stamped stem: 'As on 1 April (year), who held the office of …'. That fixes the ambiguity but not the shelf life, so such items must be flagged for retirement at the next reuse.
3. Draft a sourcing and provenance protocol that would have prevented both faults, and say what must be recorded in the item metadata.
Read the worked answer
Protocol (apply to every factual item at the point of keying):
- Two independent official sources must agree before a key is fixed. If two permitted sources conflict, the item is dropped, not adjudicated by preference.
- Recency beats convenience: where an older PDF and a newer live portal disagree on an administrative figure, the newer dated source wins - but the conflict itself is a signal that the fact is revision-prone.
- No undated document may key an item. Every source must carry a visible date.
- Coaching material, social media summaries and unverified compilations are never keying sources; they may only suggest what to check officially.
- Volatile items carry an expiry date and are pulled at the next reuse, not silently carried forward.
- Maintain a re-verification list: every office-holder, rank, count, or record-based item is re-checked before each batch, with the checking date logged.
Metadata to record per item: source name, full URL, access date, publication date, volatility tag (stable / revision-prone / date-bound), expiry date if any, and the name of the verifier. This makes the next reuse a ten-minute audit rather than a fresh guess, and it creates an audit trail if a candidate challenges a key.
