Which of the following statements about minerals is false

A. a mineral can only break in one way

Explanation:

Cleavage is the ability of crystals to break along preferred crystallographic directions with the formation of a glossy surface. In the characterization of minerals the cleavages are described as:

• perfect cleavage: crystal separates into perfect surface plates (eg micas)

• good cleavage: separation takes place in certain directions, often forming stepped surfaces (eg calcite, cyanite)

• distinct cleavage: when the formation of equal and uneven surfaces by breaking occurs (eg feldspars, hornblende)

• imperfect cleavage: cleavage surfaces are uneven (eg beryl)

• missing cleavage: no cleavage plan (eg quartz)

Minerals may have cleavage surfaces on:

a) 3 directions - eg calcite, galena

b) 2 directions - Ex .: feldspar

c) 1 direction - Ex .: micas, talc

d) absent - eg quartz, tourmaline

Future is very uncertain

Explanation:

Future of earth based on the question as if the Earth has 200 million years shortly. Three basic concepts like Global Tectonics, North American Geology and Human evolution.

In the course of all the above topics I would conclude that earth plates would collide and form another giant landmass that like the Pangaea, and as matter of fact the closing of pacific ocean will lead to the creation of great tectonic rift along the North American plate boundary and this will lead to another phase of evolution in the history of the earth. This will alter the way we see the world. The cyborg human body needs more time to develop and adjust to technology and other advancements that would occur at this period, and that rampant technology will set another level of evolution but still even the artificial intelligence of today is completely different and difficult to achieve so a close syn in-between device and man would altogether complicate the earth flow of  resources and render it unstable and use less. Besides cyborgs don't need any atmosphere to work are highly genetically modified and advanced beings, so predicting that based on media or genetic mutations can be dangerous and unauthentic.
