Answer: The two possible study design are; "COHORT STUDY" and "CROSS-SECTIONAL STUDY".

Explanation: Cohort study design is an observational study in which people who receives a particular treatment or are under a particular condition, are been observed and studied. This type of research model also allows a researcher to compare people affected by a condition to people unaffected by the same conditions.

The investigator is likely to use the cohort design because it will help in studying the children that are always exposed to smoke, and to observe the affected and unaffected children.

The CROSS-SECTIONAL design is an observational study in which a specific population are studied at a particular time. This type of research allows the researcher to study the difference in that population at a time interval.

This study design is likely to be used by the investigator, because it will help the investigator to determine the amount of secondhand smoke each child inhale at a particular time. It will also help the investigator to know the outcome of each child after 5years

What are the three things the Mormons did to the wild, dry terrain into a prosperous place
weeeeeb [17]

Explanation:

The Mormon pioneers were known as very hard working and industrious people. They were very well organized and had great faith that God was on their side and therefore they could succeed. From their struggles, they learned to work together to survive. Immediately after they arrived, they plotted out a city and began digging irrigation lines from mountain streams to the valleys below. Crops were planted before homes were built.

People were organized into companies to settle various areas which would produce different items based on the climate - those sent to southern Utah grew cotton and raised silkworms; Northern Utah was ideal for dairy farming; Central Utah had areas for mining and timber. They worked together to build homes, often many families would share a small cabin until more could be built. Because timber was hard to find and nails were extremely rare, they made do with what they had, making adobe homes and lashing wood frames together with hides.

Rather than become dependent on expensive shipments from the East, they made their own materials (including yarn and fabric!) and sold the excess to those traveling further west to California and Oregon. It took a lot of faith and hard work, but the Mormon pioneers turned what was practically a barren wasteland into a thriving and prosperous place.
