The correct answer is Composite, Arch, Whorl, Loop. This answer correctly identifies the four types of fingerprints. A composite fingerprint is a combination of two or more patterns, such as a loop and a whorl. An arch fingerprint has ridges that slope upward in the center. A whorl fingerprint has circular or spiral patterns. A loop fingerprint has ridges that enter from one side, form a loop, and exit from the same side.

What leaves a fingerprint behind?
- A.
  
  Dust
- B.
  
  Oils
- C.
  
  Dirt
Correct Answer
B. Oils

Explanation
Oils can leave a fingerprint behind because they have a greasy texture that can easily transfer onto surfaces. When a person touches an object with oily fingers, the oils from their skin can be left behind, forming a visible fingerprint. This is because oils do not evaporate quickly like water, allowing them to leave a lasting mark. Dust and dirt can also leave marks, but oils are more likely to leave a distinct fingerprint due to their unique properties.

Explanation
From a footprint, we can determine the weight of the owner based on the depth and pressure of the print. Additionally, we can identify the make of the shoe by examining the pattern and design of the sole. Lastly, the size of the shoe can be inferred by measuring the length and width of the footprint.

How do you provide permenant evidence?
- A.
  
  Draw it.
- B.
  
  Paint it.
- C.
  
  Video it.
- D.
  
  Photograph it.
- E.
  
  Don't do anything.
Correct Answer
D. Photograph it.

Explanation
Photographing provides a permanent form of evidence as it captures an image that can be stored, shared, and referenced indefinitely. Unlike drawing or painting, which are subjective and can be altered or lost over time, a photograph captures an objective representation of the evidence. Videos can also be altered or deleted, whereas photographs are more difficult to manipulate. Therefore, photographing is the most reliable and effective way to provide permanent evidence.

What do you use to make a cast?
- A.
  
  Plaster of Paris.
- B.
  
  Playdough.
- C.
  
  Cement.
- D.
  
  Nothing, you photograph it.
- E.
  
  Dig it up.
Correct Answer
A. Plaster of Paris.

Explanation
Plaster of Paris is commonly used to make casts because it is a versatile and easy-to-use material. It can be mixed with water to create a moldable paste that hardens quickly and retains its shape. Plaster of Paris is commonly used in medical settings to create casts for broken bones or orthopedic supports. It is also used in art and crafts to create molds and sculptures. Playdough is not suitable for making casts as it is not as durable or strong. Cement is too heavy and not moldable enough for this purpose. Photographing or digging up something does not involve making a cast.

How does the electrostatic print work?
- A.
  
  All of the dust stick onto the peice of paper.
- B.
  
  All of the dust sticks to the black plastic and foil.
Correct Answer
B. All of the dust sticks to the black plastic and foil.

Explanation
Electrostatic printing works by using static electricity to attract and hold toner particles onto a surface. In this case, the black plastic and foil are likely treated with a static charge, causing the dust particles to be attracted to and stick onto them. This allows for the creation of a printed image or pattern on the plastic and foil surface.

Why do SOCOs have to wear protective clothing?
- A.
  
  To look good.
- B.
  
  To protect the scene.
- C.
  
  So they are waterproof.
Correct Answer
B. To protect the scene.

Explanation
SOCOs (Scene of Crime Officers) have to wear protective clothing to protect the scene. Crime scenes can contain various hazards such as blood, bodily fluids, chemicals, or other potential contaminants. Wearing protective clothing, such as gloves, masks, and coveralls, helps to prevent the contamination of evidence and ensures the integrity of the crime scene. Additionally, protective clothing also helps to minimize the risk of cross-contamination between different crime scenes, ensuring the accuracy and reliability of forensic analysis.
