In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Example Input: Context: Allergic rhinitis (AR) is a complex chronic inflammatory disease of the nasal mucosa, caused by an interaction between genetic and environmental factors. As evidence suggests that some genetic variants may increase susceptibility to both AR and asthma, the objective of this study was to identify asthma susceptibility variants associated with AR in the Chinese population.', 'A cohort of 402 individuals with physician-diagnosed AR and 416 healthy controls were recruited from the Han Chinese population in Beijing. DNA was extracted from the peripheral blood and a total of 12 single-nucleotide polymorphisms (SNPs) shown to be associated with asthma in Japanese subjects were selected for genotyping using the SequenomMassARRAY technology platform.', 'Analysis of frequency differences of allele between the AR patients and control subjects showed that the C allele of rs204993 in the pre-B-cell leukemia homeobox 2 (PBX2) gene from the 6p21.3 locus was significantly associated with AR (p = 0.0006, pcorrected = 0.0340). Genotype analysis further confirmed the difference in distribution of this variant between AR patients and controls in the both the dominant (pT/C+C/C vs T/T = 7.37×10(-5) ) and co-dominant (pT/C vs T/T = 1.98 × 10(-4) , pC/C vs T/T = 0.004) models.\Question: Does variant of PBX2 gene in the 6p21.3 asthma susceptibility locus is associate with allergic rhinitis in Chinese subjects?
Example Output: These results suggest that the PBX2 gene in the 6p21.3 asthma susceptibility locus may be associated with increased risk for both AR and asthma in Chinese subjects.

Example Input: Context: Some subjects with suspected asthma and a negative exercise challenge test (ECT) demonstrate improved expiratory flow rates after administration of bronchodilators (BD) at the end of the ECT (unpublished observation). This study investigated whether this response predicts the presence of bronchial hyperreactivity (BHR).', 'The study population included 133 young adults (29.4% women) 21.1 +/- 4.2 years of age who underwent ECT and a methacholine challenge test (MCT). A receiver-operator-characteristic curve was used to calculate the optimal cutoff level of the response to BD as a predictor of BHR according to MCT.', 'Using a MCT cutoff level of PC(20) </= 4 mg/mL showed BHR in 12.8% of subjects. Failure to improve FEV(1) by 8% after BD administration predicted the absence of BHR with sensitivity, specificity, and positive and negative predictive values of 76.5%, 68.4%, 25.3%, and 95.5%, respectively. Avoiding MCT in subjects with less than 8% response to BD would have saved 62.5% of the MCTs and would have missed only four (3%) patients with BHR.\Question: Does response to bronchodilators after exercise challenge predict bronchial hyperreactivity?
Example Output: BD should be administered routinely after ECT, as the response may be used as a simple, inexpensive tool to predict BHR in young patients and may substantially reduce the number of unnecessary MCTs.

Example Input: Context: There is a higher likelihood of crashes and fatalities when an adolescent drives with peer passengers, especially for male drivers and male passengers. Simulated driving of male adolescent drivers with male peer passengers was studied to examine passenger influences on distraction and inattention.', "Male adolescents drove in a high-fidelity driving simulator with a male confederate who posed either as a risk-accepting passenger or as a risk-averse passenger. Drivers' eye movements were recorded. The visual scanning behavior of the drivers was compared when driving alone with when driving with a passenger and when driving with a risk-accepting passenger with a risk-averse passenger.", "The visual scanning of a driver significantly narrowed horizontally and vertically when driving with a peer passenger. There were no significant differences in the times the drivers' eyes were off the forward roadway when driving with a passenger versus when driving alone. Some significant correlations were found between personality characteristics and the outcome measures.\Question: Does peer passenger influence on male adolescent drivers ' visual scanning behavior during simulated driving?
Example Output:
The presence of a male peer passenger was associated with a reduction in the visual scanning range of male adolescent drivers. This reduction could be a result of potential cognitive load imposed on the driver due to the presence of a passenger and the real or perceived normative influences or expectations from the passenger.
