everyday-logic | choosing between routes | mimo-v2.6-flash | Marta commutes by bike: 6 km via the park or 4 km via Main Street. The park route averages 15 km/h; Main Street has traffic lights that cut her average speed to 10 km/h. Which route gets her to work faster, and by how many minutes? | Park route: 6 km ÷ 15 km/h = 0.4 h = 24 minutes. Main Street: 4 km ÷ 10 km/h = 0.4 h = 24 minutes. Both routes take the same time.

cause-effect | why an everyday thing happens | mimo-v2.6-flash | A baker notices her bread rises faster in summer than in winter, even though she uses the same yeast and flour. Why does warmer kitchen temperature make the bread rise faster? | Yeast is a living organism that feeds on sugar and releases carbon dioxide gas, which makes dough rise. Chemical reactions in yeast speed up when it is warmer, because the yeast enzymes work faster and the yeast cells are more active. In a warmer kitchen, the yeast consumes the sugars more quickly and produces gas more... | warmer temperatures increase yeast activity and enzyme reaction rates, so yeast produces carbon dioxide more quickly, making dough rise faster | true | [

What is Priya's job? | Lena fixes wiring, so she's the electrician. Tom can't cook and isn't the chef, so Tom is the nurse. That leaves Priya as the chef.

Maya has 4 liters of pear juice but only 1 liter of rum available. If she uses all 1 liter of rum and scales the recipe accordingly, how many liters of ginger ale does she need? | Since the recipe has 1 part rum, using all 1 liter of rum means she's making the recipe at full scale: 3 parts pear juice = 3 liters (she has 4, so enough), 1 part rum = 1 liter, and 2 parts ginger ale = 2 liters.

Deal B gives 5 albums for 385 crowns, i.e. 77 crowns each.

cause-effect | simple physical reasoning | mimo-v2.6-flash | Mara sets a sealed metal kettle on a hot stove. After several minutes the kettle's flat bottom bulges slightly outward.
