The <u>control class</u> acts as a switchboard between the view layer and the domain layer.
Explanation:
As the name suggests, the control class is responsible for performing the control actions. The view layer defines the entities and attributes which have to be viewed and their structural organization. 
The domain layer consists of all the entities, attributes, and relations in the data. The control class controls the flow of information between the two layers and performs the operations of filtering and selecting the content to be displayed.

Tech a says that a direct tpms system uses a pressure sensor located in each wheel. This is a TRUE statement.
Explanation:
- A tire-pressure monitoring system (TPMS) is an electronic system designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. A TPMS reports real-time tire-pressure information to the driver of the vehicle, either via a gauge, a pictogram display, or a simple low-pressure warning light.
- Direct TPMS uses a sensor mounted in the wheel to measure air pressure in each tire. When air pressure drops 25% below the manufacturer's recommended level, the sensor transmits that information to your car's computer system and triggers your dashboard indicator light.
- Mounted inside a tire assembly on valve stems or wheel rims, the sensors are usually powered by 3-volt lithium ion batteries, but some use 1.25-volt nickel metal hydride batteries. There are developments underway that promise battery-less sensors in the future, having the potential to dramatically change TPMS markets
- The tire pressure monitor system that uses a valve-stem-type transmitter is the direct reading type of TPMS.

Answer
Dog breeds = observations, Average weight and energy level for each breed = variables. Each cluster is a category. 
Explanation:
Using a method of clustering, she would be putting the dog breeds that are more similar together and in order to do this she has to look at various factors such as observation which are the dog breeds, and the average weight and energy level of the breeds, which represents variables. Every one of these clusters would be a category.
