True. They have tools to do so.
I hope i helped!
Sorry its a very long answer-
1.) Failure to maintain the rule of law
The government's repeated failures to bring levels of violent crime under control contributed to an environment which saw people resort to violence without fear of arrest or successful prosecution.
2.) Border control
3.) Corruption
4.) Employment
5.) Education
This has been government's biggest failure and carries much of the blame for the high unemployment levels. It is arguable whether current state education is in its totality any better than that under apartheid. Only 1% of black matriculants achieve a good HG maths pass.
The education system is a good example where policy failures in one area compounded those in another.
6.) Slowing economic growth
7.) Foreign policy
8.) Service delivery
9.) Race relations
Nutritional value facts are usually at the side of the container which you bought, they give you the trans fat, calories, serving size, sodium, sugar, cholesterol, carbohydrates (carbs), protein, and the type of vitamins found.

Fuel cells can make an electricity from a simple electrochemical
reaction in which oxygen and hydrogen combine to form water. There are several
different types of fuel cell but they are all based around a central design
which consists of two electrodes, a negative anode and a positive cathode.
These are separated by a solid or liquid electrolyte that carries electrically
charged particles between the two electrodes. A catalyst, such as platinum, is
often used to speed up the reactions at the electrodes. Fuel cells are
classified according to the nature of the electrolyte. Every type needs
particular materials and fuels and is suitable for any applications. The
article below uses the proton exchange membrane fuel cell to illustrate the
science and technology behind the fuel cell concept but the characteristics and
applications of the other main designs are also discussed. Proton Exchange Membrane Fuel Cells (PEMFC)
The hydrogen ions permeate across the electrolyte to the
cathode, while the electrons flow through an external circuit and provide
power. Oxygen, in the form of air, is supplied to the cathode and this combines
with the electrons and the hydrogen ions to produce water. These reactions at
the electrodes are as follows:
Anode: 2H24H+ + 4e-
Cathode: O2 + 4H+ + 4e- 2H2O
Overall: 2H2 + O22H2O + energy
PEM cells operate at a temperature of around 80°C. At this
low temperature the electrochemical reactions would normally occur very slowly
so they are catalysed by a thin layer of platinum on each electrode.
