An individual would require fewer skills in order to work in the maintenance and operations phase of construction than in the design and construction phase.

TRUE

Explanation:

The answer is true. For any construction project, it is the beginning phase where it requires conceptualization skills and designing skills. The initial designing as well as the conceptualization to commissioning of the project is very crucial phase and more skilled and experienced work force is required to carry on the project. The employees should be aware of the technical parameters of the work.

After the construction phase, it is easier for the maintenance and operational work. So here less skills are required. And hence an employee needs less skills to work in maintenance and the operational phase as compared to the designing and construction phase.

b. niger

explanation:

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
