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.

Input: Consider Input: Context: The aim of this article is to develop the Spanish adaptation of the internal functioning of Work Teams Scale (QFI-22).', 'The scale was adapted from the French version, and was applied to a sample of 1,055 employees working for firms operating in Spain. The article analyses the internal structure (exploratory and confirmatory factor analysis) and internal consistency, and provides convergent validity evidence of the scale.', 'The QFI-22 scale shows the same internal structure as the original. Factor analysis confirmed the existence of two factors: interpersonal support and team work management, with good internal consistency coefficients (α1 = .93, α2 = .92). Regarding validity evidence, the QFI-22 scale has significant correlations with other correlates and alternative scales used for comparison purposes. The two factors correlated positively with team vision, participation safety, task orientation and support for innovation (Team Climate Inventory, TCI scale), with progressive culture (Organisational Culture, X-Y scale), and with creating change, customer focus and organisational learning (Denison Organizational Culture Survey, DOCS scale). In contrast, the two factors correlated negatively with traditional culture (X-Y scale).
Answer: The QFI-22 scale is a useful instrument for assessing the internal functioning of work teams.

Output: Does spanish adaptation of the internal functioning of the Work team Scale ( QFI-22 )?


Input: Consider Input: Context: DNA methylation at CpG dinucleotides is modified in tumorigenesis with potential impact on transcriptional activity.', 'We used the Illumina 450 K platform to evaluate DNA methylation patterns of 50 metastatic melanoma tumors, with matched gene expression data.', 'We identified three different methylation groups and validated the groups in independent data from The Cancer Genome Atlas. One group displayed hypermethylation of a developmental promoter set, genome-wide demethylation, increased proliferation and activity of the SWI/SNF complex. A second group had a methylation pattern resembling stromal and leukocyte cells, over-expressed an immune signature and had improved survival rates in metastatic tumors (p < 0.05). A third group had intermediate methylation levels and expressed both proliferative and immune signatures. The methylation groups corresponded to some degree with previously identified gene expression phenotypes.
Answer: Melanoma consists of divergent methylation groups that are distinguished by promoter methylation, proliferation and content of immunological cells.

Output: Are dNA methylation subgroups in melanoma associated with proliferative and immunological processes?


Input: Consider Input: Context: The importance of angiogenesis in melanoma has been controversial and is not homogeneous. Mast cell density (MCD) is highly correlated with the extent of both normal and pathological angiogenesis, such as that in chronic inflammatory diseases and tumours.', 'We evaluated the prognostic significance of tumour microvascular density (MVD) and MCD in 25 advanced melanoma patients after resection and a 4-5-year follow up: 48% of the patients were alive and free of metastases (good prognostic subgroup); 16% had developed regional nodal metastases (intermediate prognostic subgroup); and 36% had died (poor prognostic subgroup). Tissues samples were investigated immunohistochemically to count microvessels and mast cells with an antifactor VIII and an antitryptase antibody, respectively.', 'Immunohistological staining showed a higher number of microvessels and mast cells in melanoma lesions of poor prognosis as compared with intermediate prognosis and with good prognosis, respectively.
Answer: These data agree with those showing a close relationship between MCD and angiogenesis during tumour progression and demonstrate, for the first time, a prognostic significance of MCD in human melanoma.


Output: Do tumor vascularity and tryptase-positive mast cells correlate with a poor prognosis in melanoma?
