The problem: Answer a question about this article:
The Swiss climate is generally temperate, but can vary greatly between the localities, from glacial conditions on the mountaintops to the often pleasant near Mediterranean climate at Switzerland's southern tip. There are some valley areas in the southern part of Switzerland where some cold-hardy palm trees are found. Summers tend to be warm and humid at times with periodic rainfall so they are ideal for pastures and grazing. The less humid winters in the mountains may see long intervals of stable conditions for weeks, while the lower lands tend to suffer from inversion, during these periods, thus seeing no sun for weeks.
What can the lower lands, suffering from inversion, sometimes lack for weeks?
****
The answer: sun

Zinc is highly toxic in parrots and poisoning can often be fatal. The consumption of fruit juices stored in galvanized cans has resulted in mass parrot poisonings with zinc.

The major and native language spoken in the Punjab is Punjabi (which is written in a Shahmukhi script in Pakistan) and Punjabis comprise the largest ethnic group in country.
