Question

advanced modification
10 scientists believe that some alterations are as safe as the traditional method of slow plant breeding for improved food plants. there are genetically altered products that we have been using for at least 10 years without ill effect. bakers yeast that produces more bubbles is one example.
11 however, today some of the genetic modifications to food are on a more advanced level, such as creating golden rice that provides extra vitamin a to combat blindness and death in malnourished children, or breeding a new type of sweet potato that has extra beta carotene (which the body converts to vitamin a). a new kind of tomato was bred to resist rotting and give it a longer shelf life. potatoes are bred to produce more starch. soybeans, one of the most common processed - food ingredients, are also one of the most modified food products. soybeans have been genetically modified to resist

Explanation:

The phrase "without ill effect" means that when using or consuming something (in this context, genetically modified food), there are no negative consequences such as people getting sick. Option D ("with people becoming sick") is the opposite of "without ill effect". Option A ("without positive benefits") is about benefits, not the "ill" (negative) aspect. Option B ("without negative consequences") is close but "ill effect" specifically refers to health - related negative consequences (like getting sick). Option C ("with many surprises") is not related to the meaning of "without ill effect".

Answer:

D. with people becoming sick
