Answer:

High reliability and low validity

Komok [63]

Answer:

The specific reasons are below

Explanation:

1) loud music on the street distracts the local bus drivers which will lead to accidents.

2) The blind people also lose their concentration while crossing zebra lines

3) the small kids mentally always in their own world get distracted and make big blunders and may fall in potholes.

Now, the reasons why we can't let our pet to other rooms:

1) pets are very sensitive by nature, thus any change in their usual surrounding may disturb their usually cool nature.

2) pets usually can't trust each and everybody,due to their sharp instincts, so they can never mingle with other people immediately.

3) the other reason is they don't intake food or water from strangers.

4) Also the skin of the pets are very fragile, thus letting them out to other rooms may cause them various types of bacterial and viral infections.
