Match the following food items with the nutrients they are commonly associated with:
Analyzing each food item for associated nutrients.
A (Lablab): Often associated with enriched protein content due to its legume family characteristics, thus A matches with II.
B (Golden Rice): Genetically engineered to be rich in Vitamin A, specifically beta-carotene, hence B matches with I.
C (Pumpkin): Well-known for its high Vitamin A content, notably beta-carotene, making C a match with IV.
D (Bitter gourd): Recognized for its high Vitamin C content, D matches with III.
The percentage error in the measurement of mass and velocity are 3% and 4% respectively. The percentage error in the measurement of kinetic energy is:
If \( L, M, N \) are the midpoints of the sides PQ, QR, and RP of triangle \( \Delta PQR \), then \( \overline{QM} + \overline{LN} + \overline{ML} + \overline{RN} - \overline{MN} - \overline{QL} = \):
