A portable food adulteration sensor has been introduced to detect food contamination within 30 seconds. This device can identify multiple adulterants in different food items, ensuring food safety and minimizing health risks. It is designed for both domestic and commercial use and does not require specialized training. Scientists highlight its efficiency, accuracy, and ability to provide instant results. However, the sensor's performance may vary depending on the type and concentration of adulterants present in the food sample. Which of the following can be inferred from the given information? I) The sensor can detect only one type of adulterant per test. II) The device is designed for single-use only and must be discarded after testing. III) Restaurant food is more likely to contain adulterants than home-cooked food. IV) If a sample contains multiple adulterants, the detection time may exceed 30 seconds. V) The sensor's efficiency depends on the type and concentration of adulterants present.
