You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Context: Architecturally, the school has a Catholic character. Atop the Main Building's gold dome is a golden statue of the Virgin Mary. Immediately in front of the Main Building and facing it, is a copper statue of Christ with arms upraised with the legend 'Venite Ad Me Omnes'. Next to the Main Building is the Basilica of the Sacred Heart. Immediately behind the basilica is the Grotto, a Marian place of prayer and reflection. It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858. At the end of the main drive (and in a direct line that connects through 3 statues and the Gold Dome), is a simple, modern stone statue of Mary.
Question: To whom did the Virgin Mary allegedly appear in 1858 in Lourdes France?
Solution: Saint Bernadette Soubirous
Why? This is the correct answer. Because the question is asking for the name of the person and following sentence from the passage answers it: It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858.

New input: Context: Acute lung injury is a life-threatening condition characterized by surfactant dysfunction and raised secretory phospholipase A2 (sPLA2) activity. Varespladib is a sPLA2 inhibitor shown to be effective in animal models of acute lung injury. We aimed at investigating the effect of co-administration of surfactant and varespladib on sPLA2 activity. Alveolar macrophages were cultured and stimulated with lipopolysaccharide and then treated with either varespladib, surfactant, varespladib followed by surfactant or nothing. sPLA2 activity, free fatty acids, tumour necrosis factor- (TNF-) and protein concentrations were measured in culture supernatants. Treatment with varespladib (p=0.019) and varespladib + surfactant (p=0.013), reduced the enzyme activity by approximately 15% from the basal level measured in the untreated cultures. Surfactant, varespladib and varespladib + surfactant, respectively decreased free fatty acids by -45% (p=0.045), - 62% (p=0.009) and -48% (p=0.015), from the baseline concentration of the untreated cultures. Varespladib and poractant- co-administration reduces sPLA2 activity and free fatty acids release in cultured rat alveolar macrophages, although a clear drug synergy was not evident. Since co-administration may be useful to reduce inflammation and surfactant inactivation in acute lung injury, further in vivo studies are warranted to verify its clinical usefulness.
Question: Which enzyme is inhibited by Varespladib?
Solution:
secretory phospholipase a2
