What is the middle gravity grain code?

• A. 1234
• B. 3742
• C. 7423
• D. 4273

Answer: (D)

The middle two digits in a grain code carry the gravity grade. To find the correct code, look for the one whose center pair of digits matches the required gravity value. Here, the target gravity is 27, so the code that has 2 and 7 in the middle is the best match. The other candidate codes place different middle digits (such as 23, 74, or 42), which don’t align with 27. The outer digits are usually just identifiers and don’t affect the gravity grade.
