Please read the Results—Oligosaccharide Identification and Concentration section and Figure 1 in Smith et al. (2026) below. Which of the following statements is FALSE? Smith GO, Lengyel M, Molnar-Gabor D, Greathead HMR, McDermott K. The colostrum chronicles: identifying porcine milk oligosaccharides in colostrum and investigating their role in litter performance. J Anim Sci. 2026 Jan 8;104:skag098. doi: 10.1093/jas/skag098.  Oligosaccharide Identification and Concentration Total oligosaccharide concentrations ranged from 0.827 g/L to 4.32 g/L with a mean value of 2.17 ± 0.764 g/L. The most abundant compound across all sows was 3′ SL with mean concentration of 1.14 ± 0.498 g/L. The next three most abundant were all unconfirmed compounds; S-LN-Tri (0.282 ± 0.310 g/L), GL1 (0.268 ± 0.197 g/L), and GL2 (0.217 ± 0.0770 g/L). Six of the 11 identified compounds were present in particularly low concentrations (< 0.1 g/L); these were 6' SL, 2' FL, LNnT, LNnH, LSTc, and SLNnH. The concentrations of the identified porcine milk oligosaccharides (PMO) are presented in Figure 1. Exact concentrations of each PMO for each sow can be seen in Supplementary Material (Table S1).

Please read the Results—Plasma Antioxidant Activity section and Table 4 in Lu et al. (2025) below. For GPX (glutathione peroxidase), which two groups are significantly different from each other? Plasma Antioxidant ActivityThe activities of TAC, GPX, and CAT increased (P < 0.05) quadratically, and the MDA concentration decreased (P < 0.05) quadratically with increasing RYRE content (Table 4). The goats were fed a basal diet (CON) or a diet supplemented with 1, 2, or 3 g/kg of RYRE.

Which section of a research article typically provides detailed information about the experimental design and statistical analysis?

A three-phase induction motor is supplied from a 400 V (line-to-line), 60 Hz network. The measured line current is I = 15.2 A, the measured active input power is P₁ = 8.6 kW, and the shaft (output) power is P₂ = 7.5 kW. What is the motor’s EEFRMS?
