- A.
  
  Coffee
- B.
  
  Water
- C.
  
  Juice
- D.
  
  Tea
Correct Answer
A. Coffee

Explanation
Drinking coffee after consuming alcohol is not recommended because it can further dehydrate the body. Alcohol already has a diuretic effect, causing increased urine production and fluid loss. Coffee, being a diuretic as well, can exacerbate this dehydration. It may also increase the effects of alcohol, leading to increased heart rate and blood pressure. Therefore, it is advisable to avoid coffee after drinking alcohol and opt for hydrating options like water, juice, or tea instead.

One inch =_____ cm?

Correct Answer
2.54

Explanation
One inch is equal to 2.54 centimeters. This conversion factor is commonly used to convert measurements between the imperial system (inches) and the metric system (centimeters). It is based on the international inch defined by the International Yard and Pound Agreement of 1959, which established the value of one inch as exactly 2.54 centimeters. Therefore, if you want to convert inches to centimeters, you can multiply the number of inches by 2.54 to get the equivalent measurement in centimeters.

How often does Comet Halley appear once?

Correct Answer
Every 76 years

Explanation
Comet Halley appears once every 76 years. This means that it takes approximately 76 years for Comet Halley to complete one orbit around the Sun and return to its closest point to Earth. The periodicity of 76 years is a result of the gravitational interactions between the comet and the planets in our solar system, causing its orbit to be elongated and take a long time to complete. This periodicity allows us to predict when Comet Halley will be visible from Earth, with the last appearance being in 1986 and the next expected in 2061.

How much is the safe distance for cars to keep when people drive on the rainy or iced road?

Correct Answer
50m

Explanation
The safe distance for cars to keep when driving on rainy or icy roads is 50m. This distance is necessary to ensure that there is enough space for the car to stop safely in case of an emergency. It also allows for better visibility and reaction time, reducing the risk of accidents. Maintaining a safe distance is crucial in these conditions as the road surface may be slippery, making it harder to stop or maneuver the vehicle.
