A. Throughout history, the most fertile areas with abundant arable land and freshwater supplies served as hearths for the development of civilizations.

Explanation:

The early cultural hearths around the world can be found near the lands that were productive for the development of man and his civilization. Some of these areas are Nile river valley, Indus river valley, Wei-Huang Valley, Ganges river, Mesopotamia and Mesoamerica. All these heartlands around the globe flourished due to the presence of rich environments in terms of rich soil types, for the domestication of crops as they were mostly seen along the river and lakes beds. Thus there has been a diffusion of culture along with these places and domesticating animals also took place due to the same feature like Christianity in fertile crescent and Islam in Saudi Arabia.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.

Amath expression is a collection of one or more terms, which are separated by the signs ( + , - , x , / ).example :   8+b8+b  or  a−3a−3in algebra, an equation is a mathematical statement with two expressions where, each expression is separated by an equal (=) sign. variables can be present on both the sides of the equality (=) sign and we use letters to denote such variables.example 1:   x=4+2x=4+2  , [here, we can observe that the variable is present only on one side of the equation].example 2:   2x+3=x+42x+3=x+4  , [here, we can observe that the variables are present on both side of the equation].
