Directions: In the question given below, a passage is given followed by five statements. Read the information and answer the question that follows.

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.

According to the given passage:

I) The sensor can detect only one type of adulterant per test. → Cannot be inferred

The passage states that the device can identify multiple adulterants, which contradicts this statement.

II) The device is designed for single-use only and must be discarded after testing. → Cannot be inferred

There is no mention of the sensor being single-use or requiring disposal after one test.

III) Restaurant food is more likely to contain adulterants than home-cooked food. → Cannot be inferred

The passage does not compare restaurant food vs. home-cooked food in terms of adulteration levels. This is an assumption, not an inference.

IV) If a sample contains multiple adulterants, the detection time may exceed 30 seconds. → Can be inferred

The passage states that the sensor's performance may vary based on the type and concentration of adulterants, which implies that detection time could be affected in certain cases.

V) The sensor's efficiency depends on the type and concentration of adulterants present. → Can be inferred

The last sentence in the passage explicitly states that the sensor’s performance depends on type and concentration of adulterants, making this a direct inference.

Thus, Both IV and V can be inferred from the given information.

Hence, "Option 2" is the correct answer.
