Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: Both diet quality (DQ) and physical activity (PA) have been shown to play a role in the prevention of functional capacity (FC) decline. Because older adults (OA) with T2D are at a higher risk of FC decline compared to their non-diabetic counterparts, our aim was to determine if DQ alone, or combined with PA is associated with FC decline in OA with T2D over a 3-year follow-up in a secondary analysis of the NuAge cohort.', "In 159 OA with T2D (mean age=75 years), FC change was calculated as the difference in FC scores at T1 and T4 measured by the SMAF (Système de Mesure de l'Autonomie Fonctionnelle). Baseline DQ was calculated from three non-consecutive 24-h dietary recalls collected at T1 using the validated Canadian Healthy Eating Index (C-HEI). PA change was calculated from Physical Activity Scale for the Elderly (PASE) as T4-T1. Associations were evaluated between FC decline and four combinations of variables: C-HEI score < or ≥70 with PASE change < or > median and analyzed by GLM while controlling for covariates.", 'Neither DQ alone nor DQ combined with PA change were associated with FC decline over follow-up.

Output: Is decline in functional capacity unaffected by diet quality alone or in combination with physical activity among generally healthy older adults with T2D from the NuAge cohort?


Input: Consider Input: Bone and antler collagen δ(13) C and δ(15) N values are often assumed to be equivalent when measured in palaeodietary, palaeoclimate and palaeocological studies. Although compositionally similar, bone grows slowly and is remodelled whereas antler growth is rapid and remodelling does not occur. These different patterns of growth could result in isotopic difference within antler and between the two tissue types. Here we test whether red deer (Cervus elaphus) bone and antler δ(13) C and δ(15) N values are equivalent, and whether intra-antler isotopic values are uniform.', 'Bone and antler were isotopically analysed from six stags that lived in a temperate maritime climate on the Isle of Rum, Scotland. Multiple antlers from different years were sampled per individual, together with a single bone sample per individual. Up to 12 samples were taken along the length of each antler (total of 25 antlers, 259 samples) so that a chronological record of the isotopic composition during antler growth could be obtained. Collagen was extracted and its δ(13) C and δ(15) N values were measured by continuous-flow isotope ratio mass spectrometry.', 'Intra-antler collagen isotope signatures vary, and show that not all antlers from an individual or a growth year are equivalent in carbon and nitrogen isotopic ratios. δ(15) N values typically increase with distance along antler length, but no overall trend is observed in δ(13) C values. An isotopic offset is visible between bone and antler, with bone δ(13) C and δ(15) N values being higher in most cases.

Output: Are red deer bone and antler collagen isotopically equivalent in carbon and nitrogen?


Input: Consider Input: Sialic acid, a key component of both human milk oligosaccharides and neural tissues, may be a conditional nutrient during periods of rapid brain growth.', 'We tested the hypothesis that variations in the sialic acid content of a formula milk would influence early learning behavior and gene expression of enzymes involved in sialic acid metabolism in piglets.', 'Piglets (n = 54) were allocated to 1 of 4 groups fed sow milk replacer supplemented with increasing amounts of sialic acid as casein glycomacropeptide for 35 d. Learning performance and memory were assessed with the use of easy and difficult visual cues in an 8-arm radial maze. Brain ganglioside and sialoprotein concentrations and mRNA expression of 2 learning-associated genes (ST8SIA4 and GNE) were measured.', 'In both tests, the supplemented groups learned in significantly fewer trials than did the control group, with a dose-response relation for the difficult task (P = 0.018) but not the easy task. In the hippocampus, significant dose-response relations were observed between amount of sialic acid supplementation and mRNA levels of ST8SIA4 (P = 0.002) and GNE (P = 0.004), corresponding with proportionate increases in protein-bound sialic acid concentrations in the frontal cortex.


Output: Does dietary sialic acid supplementation improve learning and memory in piglets?
