Cultivate Add to list Share. Cultivation is the act of caring for and growing plants. Your desire to grow your own fruits and vegetables in your backyard means that you will engage in some heavy cultivation. Commonly used.

The correct answer to this open question is the following.
Although the question does not include options, we can say the following.
Shilah is assigned a small group project. She groans when the teacher announces that the project will be given a single group grade (and that she cannot receive an individual grade) because she knows that working in teams or groups is likely to cause conflicts and problems. 
And this is a continual occurrence in many classrooms when the teacher asks students for teamwork and announces that the grade would not be individual but is going to be a group grade. Students know each other and know who is a hard worker and who is lazy. 
In this case, Shilah knows that some of the group members are known to be lazy and do not commit to the group effort. And sometimes students like Shilas have to do extra work or the work of others in order for the group to have a good grade.

The correct location on a place on the Earth is shown by using the meridians and the parallels.
The meridians are the vertical lines that are stretching from one pole to another, while the parallels are the horizontal lines that start from the Equator and make imaginary circles around the Earth in northern and southern direction. With the use of this two, we have the longitude and latitude at hand, so with a basic knowledge of cartography, every place can be located precisely on the surface of the Earth.
