Step 1
List all of your options as the row labels on the table, and list the factors that you need to consider as the column headings. For example, if you were buying a new laptop, factors to consider might be cost, dimensions, and hard disk size.
Step 2
Next, work your way down the columns of your table, scoring each option for each of the factors in your decision. Score each option from 0 (poor) to 5 (very good). Note that you do not have to have a different score for each option – if none of them are good for a particular factor in your decision, then all options should score 0.
Step 3
The next step is to work out the relative importance of the factors in your decision. Show these as numbers from, say, 0 to 5, where 0 means that the factor is absolutely unimportant in the final decision, and 5 means that it is very important. (It's perfectly acceptable to have factors with the same importance.)
Tip:
These values may be obvious. If they are not, then use a technique such as Paired Comparison Analysis to estimate them.
Step 4
Now multiply each of your scores from step 2 by the values for relative importance of the factor that you calculated in step 3. This will give you weighted scores for each option/factor combination.
Step 5
Finally, add up these weighted scores for each of your options. The option that scores the highest wins!
Wolves are a predator, meaning they keep the cattle population down. Take away wolves and you end up with more cattle. More cattle eats more grass, too much grass. The grass is eaten faster than it can grow back. Cattle are being born more quickly than being eaten by wolves. The region would ultimately become uninhabitable and nothing could live there.
Answer:
B. Commercial farming.
Explanation:
Commercial farming is a type of farming usually on a large scale and it involves growing crops for economic activities or commercial purposes, by using modern farming technology such as modern irrigation methods.
The modern irrigation methods help to maximize water usage and boosts efficiency in agricultural production. The two modern methods of irrigation are;
1. Drip irrigation system: it is one of the most widely used and efficient irrigation system and it involves laying plastic pipes with holes around the crops, thereby allowing water to seep through the holes drop by drop.
2. Sprinkler irrigation system: it involves using a hose to distribute water to a specific section of the farm. The hose can be positioned at various strategic points to water crops just like a rain.
Also, commercial farming isn't limited to crop productions as it involves livestock farming too.
Milk production, meat, fuel to energy, nutrients, and some serve as companions, transportation or aid with work.
