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.

Input: Consider Input: To evaluate whether the relationship between dietary composition and plasma lipid levels is genetically determined.', 'We have evaluated the influence of common apolipoprotein A5 (APOA5) variants (T-1131 > C, Ser19 > Trp and Val153 > Met) on plasma lipid concentrations in 117 males for whom dietary composition markedly changed and total cholesterol decreased (from 6.21 +/- 1.31 mmol/L in 1988 to 5.43 +/- 1.06 mmol/L in 1996) over an 8 year follow-up study.', 'APOA5 T-1131 > C and Val153 > Met variants did not influence the change in lipid measures over time. In Ser/Ser19 homozygotes, the plasma cholesterol was relatively stable over the years (6.1 +/- 1.2 mmol/L in 1988 and 5.6 +/- 1.0 mmol/L in 1996, -8%, P < 0.01). In contrast, in the Trp19 carriers, the decrease of the plasma cholesterol was more than 20% (6.5 +/- 1.6 mmol/L in 1988 and 5.1 +/- 1.0 mmol/L in 1996) (P < 0.001). The difference of the changes is significant (8% vs. 20%, P < 0.005). Changes in other analyzed lipid parameters have not been significantly associated with APOA5 variants.

Output: Does aPOA5 variant Ser19Trp influence a decrease of the total cholesterol in a male 8 year cohort?


Input: Consider Input: Overexpression of the human c-MYC (MYC) oncogene is one of the most frequently implicated events in the pathogenesis of hepatocellular carcinoma (HCC). Previously, we have shown in a conditional transgenic mouse model that MYC overexpression is restrained from inducing mitotic cellular division and tumorigenesis in the adult liver; whereas, in marked contrast, MYC induces robust proliferation associated with the very rapid onset of tumorigenesis in embryonic and neonatal mice.', 'Here, we show that non-genotoxic hepatotoxins induce changes in the liver cellular context associated with increased cellular proliferation and enhanced tumorigenesis. Both 5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) and carbon tetrachloride (CCl(4)) cooperate with MYC to greatly accelerate the onset of liver cancer in an adult host to less than 7 days versus a mean latency of onset of over 35 weeks for MYC alone. These hepatotoxin-enhanced liver tumors grossly and histologically resemble embryonic and neonatal liver tumors. Importantly, we found that MYC overexpression is only capable of inducing expression of the mitotic Cyclin B1 in embryonic/neonatal hosts or adult hosts that were treated with either carcinogen.

Output: Do hepatotoxin-induced changes in the adult murine liver promote MYC-induced tumorigenesis?


Input: Consider Input: Previous studies have reported that smoking abstinence rates are increased when nicotine skin patch treatment is initiated prior to the target quit smoking date, as compared with conventional treatment beginning on the quit date. We hypothesized that smoking in the presence of continuous levels of nicotine would attenuate the reinforcing effects of cigarette smoking and lead to a decline in dependence on inhaled nicotine, thus facilitating cessation.', 'This study involved four groups of smokers (n = 100 per group) who received either nicotine patch (21 mg/24 hr) or placebo patch treatment for 2 weeks before the quit smoking date, and during this period, smoked their usual brands of cigarettes or switched to low-tar and nicotine cigarettes: a 2 (nicotine patch) x 2 (cigarette type) factorial design. From the quit date on, all groups received standard nicotine patch treatment, consisting of 6 weeks of 21 mg/24 hr, 2 weeks of 14 mg/24 hr, and 2 weeks of 7 mg/24 hr. Abstinence was defined as self-report of no smoking from the quit date on, confirmed by expired-air carbon monoxide.', 'Continuous abstinence rates were approximately doubled by precessation nicotine patch treatment. The treatment mainly benefited smokers with lower levels of dependence, based on Fagerström Test for Nicotine Dependence score. All treatments were well tolerated.


Output: Does precessation treatment with nicotine patch significantly increase abstinence rates relative to conventional treatment?
