Which scenario is best for an online discussion group? 1 a teacher wants to meet with certain students immediately after class. 2 students from different schools want to talk about a community project. 3 a coach wants to meet with the football team before practice. 4 the student council wants to call a special session following last period.

The correct answer is 2. Students from different schools want to talk about a community project

Explanation

Online discussion groups are online sites where people discuss or hold conversation about specific topics through messages, as these are online groups they rely on Internet connection and because of this any person with access to internet connection that belongs to the group can participate in the discussions without the limits of a specific time or place; this means  members do not need to be in the same place or set a specific time to talk about the community project, which is something necessary for students from different schools as it might be difficult for them to have a face to face meeting, which is quite possible in the other cases.

the correct answer is 2.

a slump in geology means a mass movement process of slope failure. a mass of rock or unconsolidated material drops along a slip surface. in other words, rock layers move a short distance down the slope. the slump block is an intact block (2), without any landslide material.

in this image, 1 is the surface of rapture (scarp), 2 the slump block, 3 main scarp (crown), 4 base of rapture with debris flow.

slumps are caused by clear cutting on unstable soils and the sagging of earth, in coastal areas they are due to wave infiltration.
