Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

Q: A study was carried out on 200 patients of ages 20-40 years suffering from acute viral hepatitis. Sera were tested for markers of hepatitis B (HBsAg, and IgM anti-HBc) and hepatitis A (IgM-anti-HAV) by the ELISA technique. Sera negative for the markers of both viruses: Hepatitis A (HAV) and Hepatitis B (HBV) were subsequently tested for IGM Heterophil antibodies against Epstein-Barr virus (EBV) by the Monospot slide test to diagnose acute infectious mononucleosis and tested for anti-CMV (IgM) by ELISA technique for the diagnosis of acute Cytomegalovirus (CMV) infection. Non-A, non-B hepatitis (NANB) was diagnosed by exclusion. The results of the study showed that 133 (66.5%) patients had evidence of HBV infection, while only 9(4.5%) were diagnosed as HAV infection. EBV and CMV were the possible etiological agents of acute viral hepatitis in (3.5%) and 1%) respectively. Accordingly the Non-A, non-B hepatitis in this study amounts to (24.5%) of the acute viral hepatitis.

Q: The layers scientists recognize are pictured below (Figure 1.1). Core, mantle, and crust are divisions based on composition: 1. The crust is less than 1% of Earth by mass. The two types are oceanic crust and continental crust.Continental crust is felsic and oceanic crust is mafic. 2. The mantle is hot, ultramafic rock. It represents about 68% of Earths mass. 3. The core is mostly iron metal. The core makes up about 31% of the Earth. Lithosphere and asthenosphere are divisions based on mechanical properties: 1. The lithosphere is composed of both the crust and the portion of the upper mantle and behaves as a brittle, rigid solid. 2. The asthenosphere is partially molten upper mantle material and behaves plastically and can flow. A cross section of Earth showing the fol- lowing layers: (1) crust (2) mantle (3a) outer core (3b) inner core (4) lithosphere (5) asthenosphere (6) outer core (7) inner core.
