The tendency of minerals to break along smooth, flat surfaces is called streak fracture cleavage luster

The correct answer is: cleavage.

Cleavage is one of the types of mineral breakage. It is the tendency of a to break along smooth planes which are parallel to zones of weak bonding. Cleavage can be cubic when the break occur in three directions at right angles or it can be rhombohedral when the break occurs in three directions that are not at right angles. There is also one and two-direction cleavage.  

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
