Problem:Deoxidization is a method used in metallurgy to remove the oxygen content during steel manufacturing. In contrast, antioxidants are used for stabilization, such as in the storage of food. Deoxidation is important in the steelmaking process as oxygen is often detrimental to the quality of steel produced. Deoxidization is mainly achieved by adding a separate chemical species to neutralize the effects of oxygen or by directly removing the oxygen.

Answer this question: how entrapped bubbles of gases are removed from steel?
Solution:OK... To answer the above question, the relevant sentence is: Deoxidization is mainly achieved by adding a separate chemical species to neutralize the effects of oxygen or by directly removing the oxygen.
adding a separate chemical species to neutralize the effects of oxygen or by directly removing the oxygen.

Student A:Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes, caused by "excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water. (NOAA)". In the 1970s oceanographers began noting increased instances of dead zones. These occur near inhabited coastlines, where aquatic life is most concentrated. (The vast middle portions of the oceans, which naturally have little life, are not considered "dead zones".)

Answer this question: what causes a dead zone in the ocean?
Student B:OK... The relevant information is: Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes, caused by "excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near-bottom water.
excessive nutrient pollution from human activities coupled with other factors that deplete the oxygen required to support most marine life in bottom and near - bottom water.

Problem:The leader -- member exchange (LMX) theory is a relationship-based approach to leadership that focuses on the two-way (dyadic) relationship between leaders and followers. It suggests that leaders develop an exchange with each of their subordinates, and that the quality of these leader -- member exchange relationships influences subordinates' responsibility, decisions, and access to resources and performance. Relationships are based on trust and respect and are often emotional relationships that extend beyond the scope of employment. Leader -- member exchange may promote positive employment experiences and augment organizational effectiveness. It is widely used by many managers and is replacing many of its predecessors.

High leader–member exchange (lmx) relationships are based on?
Solution:OK... To answer the question, consider the following: The leader -- member exchange (LMX) theory is a relationship-based approach to leadership that focuses on the two-way (dyadic) relationship between leaders and followers.
the two - way ( dyadic ) relationship between leaders and followers.

Student A:Passage: Russian cosmonaut Gennady Padalka, who has spent 878 days in space over five missions, became the record holder for the most time spent in space when he surpassed, on 28 June 2015, the record of cosmonaut Sergei Krikalev, who spent 803 days, 9 hours and 39 minutes (about 2.2 years) in space over the span of six spaceflights on Soyuz, the Space Shuttle, Mir, and the International Space Station. Yuri Malenchenko is currently in second place, having spent 828 days in space on six spaceflights.

Question: Based on this passage, who has spent the most time in space?
Student B:
