question:
Context: Can you name some fossils? How about dinosaur bones or dinosaur footprints? Animal skeletons, teeth, shells, coprolites (otherwise known as feces), or any other remains or traces from a living creature that becomes rock is a fossil. The same processes that formed these fossils also created some of our most important energy resources, fossil fuels. Coal, oil, and natural gas are fossil fuels. Fossil fuels come from living matter starting about 500 million years ago. Millions of years ago, plants used energy from the Sun to form sugars, carbohydrates, and other energy-rich carbon compounds. As plants and animals died, their remains settled on the ground on land and in swamps, lakes, and seas (Figure 1.1). Over time, layer upon layer of these remains accumulated. Eventually, the layers were buried so deeply that they were crushed by an enormous mass of earth. The weight of this earth pressing down on these plant and animal remains created intense heat and pressure. After millions of years of heat and pressure, the material in these layers turned into chemicals called hydrocarbons (Figure 1.2). Hydrocarbons are made of carbon and hydrogen atoms. This molecule with one carbon and four hydrogen atoms is methane. Hydrocarbons can be solid, liquid, or gaseous. The solid form is what we know as coal. The liquid form is petroleum, or crude oil. Natural gas is the gaseous form. The solar energy stored in fossil fuels is a rich source of energy. Although fossil fuels provide very high quality energy, they are non-renewable.

Context: The Browns were making their first trip to San Diego since 2006. The game was back and forth, with neither team leading by more than one possession. The Chargers led 7-3 after the 1st quarter. On the Browns' first drive of the second quarter, QB Josh McCown threw a 34-yard touchdown pass to RB Duke Johnson to put the Browns up 10-7. The teams traded field goals, making it a 13-13 game at halftime. The Browns scored a field goal at the start of the 3rd quarter to go up 16-13. On the Chargers' next drive, QB Philip Rivers led the Chargers to a touchdown, going up 20-16 heading into the 4th quarter. After K Travis Coons kicked a field goal to cut the deficit to 20-19, Rivers led another touchdown drive to put the Chargers up 27-19. On the Browns' next drive, they reached the end zone, assisted by an incredible catch by TE Gary Barnidge on the Chargers' 1 yard line. They converted on the two point conversion to tie the game at 27-27 with just over 2 minutes remaining. The Chargers reached the Browns' 24 yard line with under 50 seconds to play. The Browns began to use timeouts until the Chargers faced 4th down with 2 seconds to play. After the Chargers called timeout, their kicker had an opportunity to win the game with a 39-yard field goal. The 39 yard game winning attempt was off to the right, and the game appeared to be on its way to overtime.. However, CB Tramon Williams was flagged for being offside during the play, giving the Chargers another attempt, this time from 34 yards. The field goal was converted, and the Chargers won 30-27. The Browns committed 12 penalties in the game, including this critical offside penalty. 
 Question: During which quarter did both teams score a field goal?
answer:
second


question:
Context: 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. 
 Question: Which virus can be diagnosed with the monospot test?
answer:

epstein-barr virus
