Tina observed the following when she tested the specific gravity of milk to check for adulteration- the specific gravity was lesser than that of pure milk. She complained to the milk vendor and the next day checked the specific gravity again. This time it came in the range of the desired specific gravity. Can we be assured that this is pure unadulterated milk?

Consider the following statements in respect of ground water aquifers: 1. Specific storage is specific capacity per unit depth of the aquifer. 2. Specific capacity is storage coefficient per unit aquifer depth. 3. Specific capacity is a constant for a given well. 4. For one-dimensional flow in a confined aquifer between two water bodies, the piezometric head line in the aquifer is a straight line. Which of the above statements are correct?
Bottled water is drinking water (e.g., well water, distilled water, mineral water, or spring water) packaged in PET Bottle or Glass Water Bottles. Bottled water is comprehensively regulated by the U.S. Food and Drug Administration (FDA) as a packaged food product. By law, the FDA regulations for bottled water must be at least as stringent as the Environmental Protection Agency standards for tap water. What inference can be drawn from the above passage?
Consider the following statements and choose the correct answer:

2. A finely divided soil holds less amount of water drawn from below than a soil with larger particles
3. Water held by capillary action is influenced by gravity
4. The gravitational water is that surplus of water which, after rain, gradually sinks downward, under the influence of gravity
