4. The snow albedo fecdback is an important detcrminant of climate response to higher atmospberic CO₂ concentration. Explain this feedback. What is the effeet of boreal forests on this feedback? (10 pt)

5. In the carly growing season, sudden frosts can kill new plant growth. This can be a critical factor in successful forest regeneration. This is mainly due to the radiative cooling in thc nightime. Which is more likely to have a successful seedling establishment, a small clearing, or a large cleareut? What is the reason for it? (10pl)

6.Which effect is relevant to the drought in tropical rainforests in South-east Asin: El Nino or La Nina? What is the reason for it? (10 pt)

7.Recently the extent of Aretic sea ice at the end of summer is frequently reported to record its lowest, which suggests the sea joe extent is gradually decreasing with a warming climate. What effect may this have on the Earth's climate? (10 pst)

8. In the boreal forest region, the vegetation type is gometimes different between norti-facing and south-facing slopes. For example, in Interior Alask cing slope is co covered by black spruce forest over er permafrost. In contrast, the south-facing slope is covered by deciduous broadleaf species on the permafirost-free soil. Explain the reason for it from the view of solar radintion and topography. (10 pt)

9.The maximum of daily mean solar radiation occurs in the Aretic and Antarctic regions seasonally, not in the equator. Explain this phenomenon and the reason why. (10 pt)

1.(20%) Given a string c consist of"!" and "I" symbols, for every right parenthesis there exists a matching left parenthesis, we said that string is a balanced parentheses sequ quence. For example, are balanced parentheses sequence. On the other hand, are not balanced parentheses sequence. Plcase implement a function balanced_ parenthese (seq) which takes one string seq as the parameter. The function wil return true if the string seg is a balanced parentheses sequence or false otherwise.
