Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Example Input: Context: Alkaline/vacuolar serine proteases comprise a major group of pan-fungal allergens from several prevalent airborne fungal species. It is of importance to characterize antigenic determinant(s) recognized by monoclonal antibodies against these major allergens.', 'The antigenic determinant of fungal serine proteases recognized by a monoclonal antibody, FUM20, was analyzed by dot immunoassay of synthetic peptides immobilized on cellulose membrane. Results obtained were confirmed by wild-type recombinant protease and its mutants. The epitopes were mapped to the structure of serine proteases by molecular modeling.', 'A linear epitope encompassing 9 amino acids from Pen ch 18 ((6)EKNAPWGLA(14)) binds FUM20. The corresponding peptide ((5)AKGAPWGLA(13)) from Rho m 2 also binds FUM20. Substitution of K6, P9 or W10 with alanine in this peptide resulted in drastic loss of FUM20 binding. Rho m 2 mutants with single K6A, P9A, P9G, W10A or W10F substitute showed negative immunoblot reactivity against FUM20. However, the Rho m 2 K6R mutant can bind FUM20. Three-dimensional structural models of the FUM20 antigenic determinants on serine proteases were constructed. The lysine residue critical for FUM20 interaction is on the surface of the proteases and solvent accessible. The critical core residue proline is located at the beginning of an alpha-helix.
Answer: The lysine, proline and tryptophan residues located on the N-terminal region of fungal serine proteases are critical core amino acid residues recognized by FUM20, a monoclonal antibody against serine protease pan-fungal allergens. These findings advance our understanding of the antigenic structures responsible for the antigenicity of serine protease allergens.
Example Output: Are lys , pro and trp critical core amino acid residues recognized by FUM20 , a monoclonal antibody against serine protease pan-fungal allergens?

Example Input: Context: Prostaglandin D2 (PGD2) and cysteinyl leukotrienes (cysLTs) are lipid mediators derived from mast cells, which activate TH2 cells. The combination of PGD2 and cysLTs (notably cysteinyl leukotriene E4 [LTE4]) enhances TH2 cytokine production. However, the synergistic interaction of cysLTs with PGD2 in promoting TH2 cell activation is still poorly understood. The receptors for these mediators are drug targets in the treatment of allergic diseases, and hence understanding their interaction is likely to have clinical implications.', 'We aimed to comprehensively define the roles of PGD2, LTE4, and their combination in activating human TH2 cells and how such activation might allow the TH2 cells to engage downstream effectors, such as neutrophils, which contribute to the pathology of allergic responses.', 'The effects of PGD2, LTE4, and their combination on human TH2 cell gene expression were defined by using a microarray, and changes in specific inflammatory pathways were confirmed by means of PCR array, quantitative RT-PCR, ELISA, Luminex, flow cytometry, and functional assays, including analysis of downstream neutrophil activation. Blockade of PGD2 and LTE4 was tested by using TM30089, an antagonist of chemoattractant receptor-homologous molecule expressed on TH2 cells, and montelukast, an antagonist of cysteinyl leukotriene receptor 1.', 'PGD2 and LTE4 altered the transcription of a wide range of genes and induced diverse functional responses in TH2 cells, including cell adhesion, migration, and survival and cytokine production. The combination of these lipids synergistically or additively enhanced TH2 responses and, strikingly, induced marked production of diverse nonclassical TH2 inflammatory mediators, including IL-22, IL-8, and GM-CSF, at concentrations sufficient to affect neutrophil activation.
Answer: PGD2 and LTE4 activate TH2 cells through different pathways but act synergistically to promote multiple downstream effector functions, including neutrophil migration and survival. Combined inhibition of both PGD2 and LTE4 pathways might provide an effective therapeutic strategy for allergic responses, particularly those involving interaction between TH2 cells and neutrophils, such as in patients with severe asthma.
Example Output: Do prostaglandin D2 and leukotriene E4 synergize to stimulate diverse TH2 functions and TH2 cell/neutrophil crosstalk?

Example Input: Context: Space-consuming mediastinal tumors can create respiratory failure.', 'We are reporting on a case of mediastinal lymphoma, which created respiratory failure in our patient. IV steroid therapy was used in our patient, who presented with end-stage respiratory failure.', 'Conservative management of our patient was possible without the application of ECMO.
Answer: In the right patient population, IV steroid treatment can avoid further deterioration of end-stage respiratory failure.
Example Output:
Does steroid treatment resolve acute respiratory failure in patient transferred for ECMO?
