Solution: a)

Solution: a)

Influenza A viruses are divided into subtypes on the basis of two proteins on the surface of the virus: hemagglutinin (HA) and neuraminidase (NA). There are 18 known HA subtypes and 11 known NA subtypes. Many different combinations of HA and NA proteins are possible. For example, an “H7N2 virus” designates an influenza A virus subtype that has an HA 7 protein and an NA 2 protein. Similarly, an “H5N1” virus has an HA 5 protein and an NA 1 protein.

All known subtypes of influenza A viruses can infect birds, except subtypes H17N10 and H18N11, which have only been found in bats. Only two influenza A virus subtypes (i.e., H1N1, and H3N2) are currently in general circulation among people. Some subtypes are found in other infected animal species. For example, H7N7 and H3N8 virus infections can cause illness in horses, and H3N8 virus infection cause illness in horses and dogs.

Solution: b)

In V-shaped recovery the economy quickly recoups lost ground and gets back to the normal growth trend-line.

The Z-shaped recovery is the most-optimistic scenario in which the economy quickly rises like a phoenix after a crash. It more than makes up for lost ground (think revenge-buying after the lockdowns are lifted) before settling back to the normal trend-line, thus forming a Z-shaped chart.

A U-shaped recovery is a scenario in which the economy, after falling, struggles and muddles around a low growth rate for some time, before rising gradually to usual levels.

A W-shaped recovery is a dangerous creature — growth falls and rises, but falls again before recovering yet again, thus forming a W-like chart.

The L-shaped recovery is the worst-case scenario, in which growth after falling, stagnates at low levels and does not recover for a long, long time.
