Based on the passage:
In a study, scientists compared the microbiomes of poorly nourished and well nourished infants and young children. Gut microbes were isolated from faecal samples of malnourished and healthy children. The microbiome was "immature" and less diverse in malnourished children compared to the better developed "mature" microbiome found in healthy children of the same age. According to some studies, the chemical composition of mother's milk has shown the presence of a modified sugar (sialylated oligosaccharides). This is not utilized by the baby for its own nutrition. However, the bacteria constituting the infant's microbiome thrive on this sugar which serves as their food. Malnourished mothers have low levels of this sugar in their milk. Consequently, the microbiomes of their infants fail to mature. That in turn, leads to malnourished babies.

Which one of the following is the most logical, rational and crucial inference that can be derived from the above passage?

Which one of the following is the most logical, rational and crucial inference that can be derived from the above passage?

Accepted Answer

Correct Option: Research on benign effects of gut bacteria on nutrition has policy implications. The passage highlights a scientific study comparing microbiomes of well-nourished and malnourished children, linking mother's milk (specifically sialylated oligosaccharides that feed gut bacteria) to microbiome maturation and childhood nutrition. It demonstrates that gut bacteria and nutrition are deeply connected, which has significant policy and public health implications regarding infant feeding and nutritional programs. Therefore, 'Research on benign effects of gut bacteria on nutrition has policy implications' is the most logical and rational inference. Other options make extreme, unjustified claims (like saying it cannot be treated, or prescribing untested dairy milk replacements instead of mother's milk).
