Which activity involves testing for gases, odors, temperatures, or roaches with approved instruments?

Explanation:
Testing a manhole means checking the atmosphere and conditions inside with approved instruments before anyone enters. This involves measuring for hazardous or flammable gases, assessing oxygen levels, noting odors that might indicate leaks, recording temperature to spot overheating or blockages, and even checking for signs of pests. Using approved, calibrated instruments ensures the readings are accurate and meet safety standards, which is essential to prevent asphyxiation, explosions, or exposure to harmful substances. The other activities listed aren't about verifying atmospheric conditions with instruments—they focus on how the manhole is designed or built, or on removing air rather than confirming safe conditions before entry.
