Given a passage, 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: Young people in Tanzania are known to access reproductive health services from a range of close-to-community providers outside formal health settings such as drug stores, village AIDS committees, traditional healers and traditional birth attendants (TBAs). However, questions remain about the quality of services such agents provide. This study investigated their capacity to provide adolescent reproductive health (ARH) services and explored their readiness and ability to integrate with the mainstream health sector through community referral interventions.', 'Thirty-five focus group discussions exploring close-to-community provider experiences and attitudes to ARH service provision were carried out in two districts in Northern Tanzania. Discussions were conducted in Kiswahili, digitally recorded, verbatim-transcribed, translated and back-translated from Swahili to English. A thematic analysis was conducted using NVivo 9.', 'The major close-to-community cadres providing reproductive health services were drug stores, traditional healers, TBAs and village health workers. They reported being the first port of call for adolescents seeking reproductive health services, but their knowledge of ARH needs was poor. They had negative attitudes to, and lacked the necessary resources for, the provision of such services for adolescents. Some were particularly unwilling to provide condom services and were prejudiced against adolescents using them. There was poor integration between the close-to-community providers and the formal health sector, further limiting their ability to provide adequate services.
Example Output: Are `` There bugs in condoms '' : Tanzanian close-to-community providers ' ability to offer effective adolescent reproductive health services?

Example Input: Cervical carcinoma is the second most common malignancy in females and most of the cases are found in developing countries. The objectives of the present study were (a): to demonstrate the antiproliferative and apoptotic effects of Achillea falcata (A.falcata) extract in human cervical cancer cells (HeLa), and (b): to study the effect of the extract on cellular morphology, cell cycle phase distribution and mitochondrial membrane potential.', 'MTT assay was used to evaluate the anticancer effect of the extract on HeLa cells. Phase contrast, fluorescence microscopy and transmission electron microscopy (TEM) were used to investigate the morphological changes in these cancer cells after extract treatment. Flow cytometry was used to evaluate the effects of the extract on cell cycle and mitochondrial membrane potential.', 'The results revealed that A. falcata extract led to a significant antiproliferative effect in HeLa cancer cells. The extract induced cellular shrinkage, chromatin condensation and appearance of apoptotic bodies which are the hallmarks of cellular apoptosis. TEM results showed that extract-treated cells had nuclear membrane which was hemispherical and the nuclear chromatin was concentrated and bundled on the inner border of karyotheca. The endoplasmic reticulum also became enlarged in the inner segment. The extract also induced G2/M phase cell cycle arrest along with loss of mitochondrial membrane potential.
Example Output: Are antiproliferative and apoptotic effects of the ethanolic herbal extract of Achillea falcata in human cervical cancer cells mediated via cell cycle arrest and mitochondrial membrane potential loss?

Example Input: Three-dimensional (3D) surface matching is a novel method to administer deep inspiration breath-hold (DIBH) radiation therapy for left-sided breast cancer to reduce cardiac exposure. We analyzed port (x-ray) films to assess patient setup accuracy and treatment times to assess the practical workflow of this system.', 'The data from 50 left-sided breast cancer patients treated with DIBH were studied. AlignRT (London, UK) was used. The distance between the field edge and the anterior pericardial shadow as seen on the routine port films (dPORT), and the corresponding distance seen on the digitally reconstructed radiographs (DRR) from the planning (dDRR) were compared as a quantitative measure of setup accuracy. Variations of dPORT - dDRR over the treatment course were assessed. In a subset of 21 patients treated with tangential beams alone, the daily treatment durations were analyzed to assess the practical workflow of this system.', 'Considering all 50 patients, the mean absolute systematic uncertainty between dPORT and dDRR was 0.20 cm (range, 0 to 1.22 cm), the mean systematic uncertainty was -0.07 cm (range, -1.22 to 0.67 cm), and their mean random uncertainty was 0.19 cm (range, 0 to 0.84 cm). There was no significant change in dPORT - dDRR during the course of treatment. The mean patient treatment duration for the 21 patients studied was 11 minutes 48 seconds. On intrapatient assessments, 15/21 had nonsignificant trends toward reduced treatment durations during their course of therapy. On interpatient comparisons, the mean treatment times declined as we gained more experience with this technique.
Example Output:
Do clinical experience with 3-dimensional surface matching-based deep inspiration breath hold for left-sided breast cancer radiation therapy?
