Science can answer many questions. I can ask it, "How long do I need to fire the engines to achieve this particular orbit", or perhaps "How much material do I need in this region of the bridge to sustain the load of traffic going across it?"
But science is not the computer from Star Trek. I can't come to science and ask it, "How long should we quarantine to minimize health impact, and maximize economic recovery?" Ultimately, that question does not have a scientific answer. It can be informed by statistics -- to the best that we understand the numbers, and scientists can present models of what they think the future will look like... but results not guaranteed.
Some problems have clear cut answers, that science can contribute concrete solutions to. Other problems do not have clear cut answers -- but have a large population of supporters claiming that all "the science" agrees with them, and to disagree with them is to shun reason.
This is also scientific illiteracy.
