Question: Read this and answer the question

DST is generally not observed near the equator, where sunrise times do not vary enough to justify it. Some countries observe it only in some regions; for example, southern Brazil observes it while equatorial Brazil does not. Only a minority of the world's population uses DST because Asia and Africa generally do not observe it.

The lack of fluctuation in time for what daily event means regions of the world near the equator don't usually keep DST?
Answer: sunrise

Problem: Compass-M1 transmits in 3 bands: E2, E5B, and E6. In each frequency band two coherent sub-signals have been detected with a phase shift of 90 degrees (in quadrature). These signal components are further referred to as "I" and "Q". The "I" components have shorter codes and are likely to be intended for the open service. The "Q" components have much longer codes, are more interference resistive, and are probably intended for the restricted service. IQ modulation has been the method in both wired and wireless digital modulation since morsetting carrier signal 100 years ago.
What are the two sub-signals in each frequency band referred to as?
The answer is the following: "I" and "Q"

After Laporta's departure from the club in June 2010, Sandro Rosell was soon elected as the new president. The elections were held on 13 June, where he got 61.35% (57,088 votes, a record) of total votes. Rosell signed David Villa from Valencia for 40 million and Javier Mascherano from Liverpool for 19 million. In November 2010, Barcelona defeated their main rival, Real Madrid 50 in El Clasico. In the 201011 season, Barcelona retained the La Liga trophy, their third title in succession, finishing with 96 points. In April 2011, the club reached the Copa del Rey final, losing 10 to Real Madrid at the Mestalla in Valencia. In May, Barcelona defeated Manchester United in the 2011 Champions League Final 31 held at Wembley Stadium, a repeat of the 2009 final, winning their fourth European Cup. In August 2011, La Masia graduate Cesc Fabregas was bought from Arsenal and he would help Barcelona defend the Spanish Supercup against Real Madrid. The Supercup victory brought the total number of official trophies to 73, matching the number of titles won by Real Madrid.
What percentage of the votes for president did Rosell get?
61.35%

Input: Wood
In the diffuse-porous woods, the demarcation between rings is not always so clear and in some cases is almost (if not entirely) invisible to the unaided eye. Conversely, when there is a clear demarcation there may not be a noticeable difference in structure within the growth ring.

What kind of wood often has ring divisions that can't even be seen by looking at it?
Output: diffuse-porous

Input: Article: Archaeologist Louis Binford criticised the idea that early hominids and early humans were hunters. On the basis of the analysis of the skeletal remains of the consumed animals, he concluded that hominids and early humans were mostly scavengers, not hunters, and this idea is popular among some archaeologists and paleoanthropologists. Robert Blumenschine proposed the idea of confrontational scavenging, which involves challenging and scaring off other predators after they have made a kill, which he suggests could have been the leading method of obtaining protein-rich meat by early humans.

Now answer this question: What did Binford conclude humans were instead of hunters?

Output: scavengers

Problem: The Alps are a source of minerals that have been mined for thousands of years. In the 8th to 6th centuries BC during the Hallstatt culture, Celtic tribes mined copper; later the Romans mined gold for coins in the Bad Gastein area. Erzberg in Styria furnishes high-quality iron ore for the steel industry. Crystals are found throughout much of the Alpine region such as cinnabar, amethyst, and quartz. The cinnabar deposits in Slovenia are a notable source of cinnabar pigments.
The cinnabar deposits are found in what area?
The answer is the following:
Slovenia
