Answer the following question given this paragraph: Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds. Q: What type of gases are the least reactive of all elements? Choices: - brave - humble - lucky - noble A:
(Answer)
noble
Ques: Answer the following question given this paragraph: We can see rainbows because they are formed by visible light. Visible light includes all the wavelengths of light that the human eye can detect. It allows us to see objects in the world around us. Without visible light, we would only be able to sense most objects by sound or touch, and we would never see rainbows. Like humans, most other organisms also depend on visible light, either directly or indirectly. Many animals use it to see. All plants use it to make food in the process of photosynthesis. Without the food made by plants, most other organisms could not survive. Q: What helps us see rainbows in the sky? Choices: - spectral light - myopia - prism - visible light A:
Ans: visible light

Answer the following question given this paragraph: Careful farming helps to keep up soil quality each season. One way is to plant different crops each year. Another is to alternate the crops planted in each row of the field. These techniques preserve and replenish soil nutrients. Planting nutrient rich cover crops helps the soil. Planting trees as windbreaks, plowing along contours of a field, or building terraces into steeper slopes all help to hold soil in place ( Figure below ). No-till or low-till farming disturbs the ground as little as possible during planting. Q: What is the purpose of utilizing careful farming practices such as rotating crops or planting nutrient rich crops? Choices: - improve sediment quality - improve photosynthesis quality - improve soil texture - improve soil quality A:
(A).
improve soil quality
Ques:Answer the following question given this paragraph: Quantities have two parts: the number and the unit. The number tells "how many. " It is important to be able to express numbers properly so that the quantities can be communicated properly. Standard notation is the straightforward expression of a number. Numbers such as 17, 101.5, and 0.00446 are expressed in standard notation. For relatively small numbers, standard notation is fine. However, for very large numbers, such as 306,000,000, or for very small numbers, such as 0.000000419, standard notation can be cumbersome because of the number of zeros needed to place nonzero numbers in the proper position. Q: Quantities have two parts: the number (how many) and what else? Choices: - the motion - the member - the credit - he unit A:

Ans:he unit
Answer the following question given this paragraph: Imagine walking in the forest in Figure below . The towering trees have been growing here for hundreds of years. It may seem as though the forest has been there forever. But no ecosystem is truly static. The numbers and types of species in most ecosystems change to some degree through time. This is called ecological succession. Important cases of ecological succession are primary succession and secondary succession. Q: The numbers and types of species in most ecosystems change to some degree through time and this is called? Choices: - physiological succession - continuous succession - environmental succession - ecological succession A:
ecological succession
