Drag each tile to the correct star. Not all tiles will be used. Identify the element present in each star based on the gaps observed in the wavelengths of its light. Refer to this table containing the absorption wavelengths (in nm) of several elements.

Element Absorption Wavelength (in nm)
helium 447, 502, 587, 668
carbon 427, 515, 600, 678
sulfur 425, 565, 639, 675
xenon 484, 590, 687
calcium 429, 527, 593, 645
silver 421, 521, 662

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
