Which of the following is redundant to answer all the above questions?

Mark answer (1) if the inference is "definitely true" i.e. it properly follows from the statement of facts given.

Mark answer (2) if the inference is "probably true" though not "definitely true" in the light of the facts given.

Mark answer (3) if the "data are inadequate" i.e. from the facts given you cannot say whether the inference is likely to be true or false.

Mark answer (4) if the inference is "probably false" though not "definitely false" in the light of the facts given.

Mark answer (5) if the inference is "definitely false" i.e. it cannot possibly be drawn from the facts given or it contradicts the given facts.

A recent report that satellite data shows groundwater levels in northern India depleting by as much as a foot per year, over the past decade, is a matter of concern. The clear writing on the wall is that India faces a turbulent water future and veritable crisis without proactive policy and sustainable practices. Besides the poor monsoon this season and the resultant drought situation pan-India calls for sustained policy focus on the water economy. A whole series of glaring anomalies do need to be addressed. For one, there's far too much reliance on groundwater. For another our water infrastructure for storage and supply is sorely inadequate.

Worse, policy distortions in artificially under pricing key agri-inputs like power have perversely incentivised cultivation of water intensive crops like paddy in traditionally wheat growing areas.

India has failed to take measures to recharge groundwater adequately in northern part.

Mark answer (1) if the inference is "definitely true" i.e. it properly follows from the statement of facts given.

Mark answer (2) if the inference is "probably true" though not "definitely true" in the light of the facts given.

Mark answer (3) if the "data are inadequate" i.e. from the facts given you cannot say whether the inference is likely to be true or false.

Mark answer (4) if the inference is "probably false" though not "definitely false" in the light of the facts given.

Mark answer (5) if the inference is "definitely false" i.e. it cannot possibly be drawn from the facts given or it contradicts the given facts.

Adequate monsoon helps in drawing less ground water for cultivation and thus preserve balance.
