Answer : Option B) The study does not include a control group.

Explanation : The experiment does not includes a control group in it, as the inclusion of control group would have been used as a benchmark to measure how the other tested results were. The biologist simply hypothesized that restricting food from mice will decrease their activity. And on the same he designed his experiment in which he observed the activity of 50 mice under restricted food regimens. And he lacked a comparison for the results, i.e the control group.

benefit

  • protection of infrastructure
  • lower insurance costs
  • employment opportunities

The flood mitigation projects have initial startup costs and ongoing maintenance costs over the years. However, apart from the costs, these have additional benefits like lower insurance costs due to protected infrastructure and  reduced flood damage, along with employment opportunities during building and maintenance.

Further Explanation:

Flooding usually happens when lots of rainfall occurs in relatively short time periods. These are usually enough to cause rivers to overflow their banks and also occur when storms force large volumes of water from the ocean to travel inland.  Typically these occur in arid ecosystems, having low average rainfall- the water accumulates in dry regions and saturates the area. This phenomena are majorly destructive and can uproot trees, destroy bridges, buildings and other infrastructure while leading to loss of life.
