Statement: Shiva told the broker that he wanted a two-sharing flat in…

Concept: In statement-and-assumption reasoning, an assumption is implicit only when the stated action or claim cannot stand without it — remove the assumption and the statement stops making sense. What is required is a modest, taken-for-granted reliance that motivates the disclosed action — that the other party will engage with and act on a stated request — not a guarantee that the outcome will actually succeed. An unstated detail the statement would work fine without, even if true, is not an implicit assumption; it is just extra information the statement never commits to.

Applying this test to the three points under Shiva's statement:

• Flats are available in the Bellyband area — Shiva's request to the broker does not need this to be true; he could be asking the broker to search for or arrange a flat that isn't yet confirmed to exist there, so the statement holds even without this being assumed.

• Shiva will live there at least for a year — the statement is only about "immediate possession", i.e. when he moves in, and says nothing about how long he intends to stay afterward, so this detail plays no role in the statement.

• The broker will sell as per Shiva's requirement — the statement's own phrase for the broker successfully delivering (arranging) a matching flat, not necessarily a formal transfer of ownership. This is the one point the statement cannot do without: telling the broker a specific requirement serves a purpose only if Shiva is relying on the broker to engage with it and act on it — a reasonable reliance that the broker will try, not a guarantee that a matching flat will actually be found.

Cross-check: The negation test confirms it — assume the broker completely ignores the requirement and does not act on it at all, and Shiva's act of telling him becomes pointless, so the statement stops making sense (this negates the reliance on the broker's engagement, not the eventual outcome — even a broker who tries and fails still made Shiva's act of telling him worthwhile). Negating either of the other two points changes nothing about why Shiva approached the broker in the first place.

Conclusion: Only the reliance on the broker to act as per Shiva's requirement is a necessary implicit assumption — Only III.
