יש את אוצה שאלה עם תשובה שונה... מה הקטע?

התשובה הנכונה היא ג (כמו שמסומן כאן). נלקח מבוחן אמצע של יחידה 5.

צריך לתקן התשובה היא well water לאחר שבדקתי גם באתר של edX

וואלה לא ידעתי שאוספים טל

מים חדשים מגיעים רק מהגשם והטל

2. Alternative (New) Water Sources: Rainwater Harvesting & Dew Collection 🌧️💧 Oh, look—Mother Nature’s free refill station, if only we’d stop turning every drop into industrial runoff. 🙃 Here’s why rainwater harvesting and dew collection earn the coveted “new water source” badge: • Beyond the Usual Suspects • Well water & surface water? Ancient history—underground aquifers and rivers have been on the menu for millennia. No brownie points for “innovation” there. • Treated wastewater & groundwater? Sure, we’re busy recycling pee and pulling from fading aquifers, but that’s just desperate damage control. • Rainwater Harvesting • Mechanics: Slap some gutters and storage tanks on your roof, and voilà—every cloudburst becomes potable (if you filter it right). • Pros: • Zero energy for abstraction—no giant pumps whining all day. • Cuts stormwater overloads and flash floods—because who doesn’t love a two‐hour deluge in their backyard? 😬 • Cons: • Seasonal moods: dry season = empty barrels and existential dread. • Contaminants from your roof—bird droppings and moss fragments, yum. • Dew Collection • Mechanics: Lay out special nets or radiative panels overnight; as the turf chills below dew point, microscopic droplets condense and trickle into your collector. • Pros: • Works in hyper‐arid zones where rain is mythical. • Silent, low‐tech elegance—like catching ghosts of humidity. 👻 • Cons: • Yield is modest—enough for one thirsty tree, not your whole lawn. • Relies on nighttime humidity swings; climate change might even kill your dew party.
