Kala added a spoon of yeast and hot boiling water to knead bread dough, whereas Rupa added warm water to knead dough with yeast in it. Both of them made bread. Whose bread will be soft? Why?

I think Rupa's bread will come out softer than Kala's.

Explanation:

Using hot boiling water to activate yeast can kill it. Instead of being absorbed by the protein, the hot water is absorbed into the starch molecules.

It is better to use warm water to get a more fluffy bread.

Soft bread is soft because CO2 produced by yeast and water that gets turned to steam by the baking process gets trapped into pockets by a mesh of gluten, causing the dough to expand. The dough then solidifies, keeping its shape. If your bread is not soft then it hasn't expanded enough for one or more reasons.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
