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: Thigmotaxis refers to a specific behavior of animals (i.e., to stay close to walls when exploring an open space). Such behavior can be assessed with the open field test (OFT), which is a well-established indicator of animal fear. The detection of similar open field behavior in humans may verify the translational validity of this paradigm. Enhanced thigmotaxis related to anxiety may suggest the relevance of such behavior for anxiety disorders, especially agoraphobia.', 'A global positioning system was used to analyze the behavior of 16 patients with agoraphobia and 18 healthy individuals with a risk for agoraphobia (i.e., high anxiety sensitivity) during a human OFT and compare it with appropriate control groups (n = 16 and n = 19). We also tracked 17 patients with agoraphobia and 17 control participants during a city walk that involved walking through an open market square.', 'Our human OFT triggered thigmotaxis in participants; patients with agoraphobia and participants with high anxiety sensitivity exhibited enhanced thigmotaxis. This behavior was evident in increased movement lengths along the wall of the natural open field and fewer entries into the center of the field despite normal movement speed and length. Furthermore, participants avoided passing through the market square during the city walk, indicating again that thigmotaxis is related to agoraphobia.
Answer: This study is the first to our knowledge to verify the translational validity of the OFT and to reveal that thigmotaxis, an evolutionarily adaptive behavior shown by most species, is related to agoraphobia, a pathologic fear of open spaces, and anxiety sensitivity, a risk factor for agoraphobia.
Example Output: Does a Human Open Field Test reveal Thigmotaxis Related to Agoraphobic Fear?

Example Input: Context: To evaluate pazopanib eye drops in subjects with active subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).', 'Multicountry, randomized, parallel-group, double-masked, active and placebo-controlled, dose-ranging study of eye drops.', 'A total of 510 subjects (93% white; 58% female; mean age, 75.3 years) whose AMD was previously managed by anti-vascular endothelial growth factor intravitreal injections.', 'Treatments administered for 52 weeks included placebo eye drops instilled 4 times daily (n=73); pazopanib 5 mg/ml instilled 3 (n=72) or 4 times daily (n=74); pazopanib 10 mg/ml instilled 2 (n=73), 3 (n=73), or 4 times daily (n=72); or ranibizumab injection administered once every 4 weeks (n=73). In addition, for all eye drop treatment groups, open-label ranibizumab was administered as needed.', 'The main outcome measures were best-corrected visual acuity (BCVA) and injection frequency assessed at week 52. Safety was assessed every 4 weeks and pazopanib plasma concentrations were determined at weeks 4 and 24.', 'At week 52, pazopanib, with allowance for as-needed ranibizumab injections, was noninferior to monthly ranibizumab as well as to as-needed ranibizumab administered with placebo eye drops in maintaining BCVA (estimated BCVA gains of 0.3-1.8 vs. 1.4 vs. 0.2 letters, respectively). Pazopanib treatment did not reduce as-needed ranibizumab injections by ≥50% (prespecified efficacy criterion). At week 52, there were no clinically meaningful changes from baseline in retinal thickness or morphology, CNV size, or lesion characteristics on optical coherence tomography or fluorescein angiography. Complement factor H genotype had no effect on the responses to pazopanib and/or ranibizumab (BCVA, injection rate, or optical coherence tomography/fluorescein angiography changes). Steady-state concentrations of pazopanib in plasma seemed to be reached by week 4. The most common ocular adverse events related to pazopanib and ranibizumab were application site pain (3%) and injection site hemorrhage (1%), respectively. No treatment-related serious adverse events were reported.
Answer: Pazopanib was well tolerated. Daily pazopanib eye drops in neovascular AMD subjects did not result in therapeutic benefit beyond that obtained with ranibizumab alone.
Example Output: Does clinical evaluation of pazopanib eye drop versus ranibizumab intravitreal injections in subjects with neovascular age-related macular degeneration?

Example Input: Context: Hyperhomocysteine is an independent risk factor of coronary heart disease (CHD). However, whether hyperhomocysteine affects the progression of atherosclerosis is unclear. In the present study, we examined the effect of hyperhomocysteine on the formation of atherosclerosis in low-density lipoprotein receptor-deficient (LDLr(-/-)) mice.', 'Forty-eight 7-week-old LDLr(-/-) mice were assigned to the following groups: mice fed a standard rodent diet (control group), mice fed a high-methionine diet (high-methionine group), mice fed a high-fat diet (high-fat group), and mice fed a diet high in both methionine and fat (high-methionine and high-fat group). At the age of 19, 23, and 27 weeks, four mice at each interval in every group were sacrificed.', 'At the end of the study, mice did not show atherosclerotic lesions in the aortic sinus and aortic surface until 27 weeks old in the control group. However, atherosclerotic lesions developed in the other three groups at 19 weeks. The amount of atherosclerotic lesions on the aortic surface was lower in the high-methionine group than in the high-fat group (P < 0.001). Atherosclerotic lesions on the aortic surface in the high-methionine and high-fat group were the most severe. The mean area of atherosclerotic lesions in the aortic sinus compared with atherosclerotic lesions on the aortic surface was lower in the high-methionine group than in the high-fat group (P < 0.001). Atherosclerotic lesions in the aortic sinus in the high-methionine and high-fat group were the most severe.
Answer: Homocysteinemia accelerates atherosclerotic lesions and induces early atherosclerosis independently in LDLr(-/-) mice. Reducing the level of homocysteinemia may be beneficial for prevention and treatment of CHD.
Example Output:
Does hyperhomocysteinemia independently cause and promotes atherosclerosis in LDL receptor-deficient mice?
