This question asks whether science by itself can end world hunger, or whether the real problem is sharing food fairly, poverty and war, which science cannot fix on its own.

The statement assumes hunger is a production problem science can solve, when the world already grows more than enough food and the binding constraints are distribution, poverty, waste and conflict.
domain: science answers the production domain decisively but not the distribution, political and economic domains where most hunger actually lives, so 'only' fails even where science succeeds.
How to approach it. Weigh whether science alone can end global hunger, testing the absolute 'only' against the fact that the world already produces enough food, so the binding constraint may be distribution and politics.
Science has largely answered the production side of hunger and continues to, but it is not the only answer and cannot be, because the world already produces enough food and people still starve, which means the unsolved problem is distribution, poverty and conflict, domains where laboratories have no jurisdiction.
As warming shrinks arable land and disrupts rainfall, drought-tolerant crops, precision agriculture and lab-grown alternatives may be the difference between feeding the world and not, so the scientific frontier matters enormously and dismissing it would be foolish. But even this concedes the deeper point, because climate-resilient technology still has to be funded, distributed and reach the poor, and it does nothing about the conflict and inequality that cause most present hunger, so it remains an answer, not the only one.
Science has answered the question Malthus asked and will be indispensable against climate stress, but it is not the only answer to hunger and never could be, because a world that wastes a third of its food while millions starve does not have a production problem, it has a distribution, poverty and conflict problem that no laboratory can solve.
Science is neither the only answer nor a uniformly benign one: it answers hunger under conditions of access, equity and good governance, but under conditions of corporate control, debt and ecological strain the same science can deepen the dependence and vulnerability that cause hunger, so its value is conditional, not absolute.
It is true that no amount of fair distribution feeds a growing population on stagnant yields, and that every realistic plan to end hunger assumes continued scientific progress, so science is not optional but foundational. This deserves full weight. But being foundational is not being sole or sufficient: a foundation needs the house built on it, and the conditions of access, equity, ecology and governance are that house, which is exactly why the word 'only' cannot stand even for a technology this important.
Science is indispensable to ending hunger but its effect is conditional, an answer under access and good governance and a hazard under corporate control and ecological strain, so the claim that it is the only answer mistakes a necessary tool for a complete solution and ignores the political conditions that decide whether the tool feeds people or fails them.
Option A runs on domain, granting science the production domain while locating hunger in distribution, poverty and conflict where science has no jurisdiction. Option B runs on conditions, arguing science answers hunger or worsens it depending on access, corporate control and ecology. Both are defensible: A is the clean 'enough food already exists' refutation of 'only'; B is the subtler argument that science itself can be part of the problem, which scores higher if the conditions are held consistently.
