Hi SimantaSourav,Your logic chain is actually spot-on. "No planning → excessive spending → mounting debt," so "planning → less of that spending → less debt" is a perfectly valid read of Statement
1. Nothing wrong there.
The issue is the bar you're setting for sufficiency. You're demanding that the statement prove
"no debt at all," but read the question stem carefully:
"Can financial budgeting
help individuals
avoid debt?"
This is a
yes/no question, and the words "can" and "help" set the bar. It is
not asking "does budgeting guarantee zero debt?" It's asking whether budgeting
can help reduce/avoid debt.
Why "reduction in debt" is enoughIn a yes/no DS question, a statement is
sufficient the moment it forces a
definite yes or a
definite no - you don't need the strongest possible outcome. Your own chain lands on: budgeting cuts the excessive spending that drives the debt. That's a definite
YES, it can help. The question is answered. That's exactly what sufficiency means here.
So "reduction in debt" isn't a weakness - it
is the yes. You'd only need "eliminates debt entirely" if the stem had asked "Does budgeting guarantee an individual never has debt?" It didn't.
Lock the habit - watch the verb in the stem- "Can X
help avoid Y?" - you need only a definite yes/no on whether it helps. A partial effect still gives a definite
yes.
- "Does X
eliminate Y?" - now you'd need proof of
complete removal.
Same statement, but the second phrasing would raise the bar. Statement
1 clears the
actual bar in this question, which is why it's
sufficient - and combined with the same logic on Statement
2, the answer is
D.
The takeaway: in yes/no DS, sufficiency means a
definite answer, not a
maximal one. Don't hand the statement a harder job than the stem gave it.
Answer: DSimantaSourav
No Financial planning => excessive spending => mounting debt
If we have financial planning => no excessive spending => reduction in debt (But how can we say for sure that there will be no debt, specifically when we are analysing the sufficiency of a statement? Should not the statement clearly point towards sufficiency)
