| 1. Water |
 |
| Water is usually defined as
a colourless, tasteless, odourless liquid. However, water
is only colourless when it is found in small quantities.
When it is frost it is whitish, and when it is accumulated
in large quantities it reflects the colours of the environment.
As for its smell and taste, they also depend on its composition.
In nature, water is never pure and always contains different
sorts of dissolved substances and materials in suspension,
which vary in quantity depending on the origin. Some water
has a strong smell and taste, due to the minerals it contains:
iron, potassium, magnesium, etc. |

| Inferring. We infer when we
try to find out what is suggested or implied in
what someone is saying. We can also infer meanings
from what we read or observe. Inferring is, therefore,
a mental activity that consists in drawing conclusions
from something. If we are skilful in inferring,
we find more meanings in our experiences. |
