aksik [14]

Answer:

12-14 october

Explanation:

The probable period of exposure is calculated as follows:

  1. Know  the range of the incubation period
  2. Start counting back from the days of the first case by subtracting the first number of incubation period range
  3. Count back the days from the last case by subtracting the last number of incubation period range.
  4. This will give a range which will be the period of exposure.

From the question,

  • Incubation period range 1-15
  • Date of first case = october 15
  • Therefore, first date of exposure = 15 -1 = 14
  • Date of last case = 22
  • Therefore, last date of exposure = 27 - 15 = 12
  • Thus, the range is 12-14 october which is the probable period of exposure.

Well drilling is another way, you get clean, natural gas by drilling into wells that connect into the ground. All that being said, we could also get chemical energy to be more safer, more usable, more efficient, and cleaner, if people were not careless with their work.
