The characteristic of a sophisticated intelligent agent demonstrates its ability to interact with users in a more natural language.

Humanlike interface

Explanation:

In simple words, Humanlike interface can be understood as the multidisciplinary branch of research that focuses on computer technologies architecture, namely the communication among people (users) and machines. HCI began with desktops and has now grown to encompass nearly all aspects of information technologies development.

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.
