Question 1

True or false: Brown rice is a genetically distinct plant from white rice.

Accepted Answer

False. Brown rice is just white rice with the bran layer intact; both come from the same plant, just processed differently.

Question 2

Question 3

True or false: All rice is gluten-free, but wild rice is not actually rice.

Accepted Answer

True. Rice (Oryza) is naturally gluten-free. Wild rice (Zizania) is botanically a different plant, not true rice. Both parts of the statement are accurate, making the entire claim true.

Question 4

True or false: Rice belongs to the grass family.

Accepted Answer

True. Rice plants are from the Poaceae (grass) family, genus Oryza. While the seeds we eat are grains, the plant is biologically a grass.

Question 5

True or false: There are over 40,000 varieties of rice in the world.

Accepted Answer

True. The International Rice Research Institute holds over 40,000 varieties in its gene bank, from long-grain to sticky rice.

Question 6

True or false: Eating raw rice is safe.

Accepted Answer

False. Raw rice can contain Bacillus cereus spores and is hard to digest; it's not recommended for safety reasons.

Question 7

True or false: Rice farming produces more greenhouse gases than all global air travel combined.

Accepted Answer

False. Rice farming accounts for ~1.5% of global greenhouse gas emissions, roughly equal to the aviation sector's contribution. While it emits significant methane, total emissions are comparable, not greater, making the claim false.

Question 8

True or false: Raw white rice can be stored for up to 30 years without spoiling.

Accepted Answer

True. When sealed in oxygen-free containers, white rice can last 25–30 years due to its low moisture content.
