Question

how does michio kaku establish the nineteenth and twentieth centuries as an \age of discovery\ in \choreographers of matter, life, and intelligence\?

by describing the government support offered to scientists of the time

by offering quantitative proof of peoples improved health and lifespans

by highlighting the social and religious developments of the era

by listing the significant scientific developments of the era

Explanation:

In the context of establishing an "Age of Discovery," scientific developments are key. Michio Kaku, as a scientist, would likely focus on scientific advancements. Government support (first option) is not the main way to establish an age as one of discovery. Quantitative proof of health (second option) is more about a result of some progress but not the core of discovery. Social and religious developments (third option) are not the typical focus for a scientific "Age of Discovery" in a work titled "Choreographers of Matter, Life, and Intelligence" which implies a scientific exploration. Listing significant scientific developments (fourth option) directly relates to what makes an age a time of discovery in a scientific - themed work.

Answer:

by listing the significant scientific developments of the era
