Problem: During the summer months, it is common for temperatures to reach over 90 F (32 C), with an average of 106.5 days per year, including a majority from June to September, with a high of 90 F or above and 4.6 days at or over 100 F (38 C). However, humidity usually yields a higher heat index. Summer mornings average over 90 percent relative humidity. Winds are often light in the summer and offer little relief, except in the far southeastern outskirts near the Gulf coast and Galveston. To cope with the strong humidity and heat, people use air conditioning in nearly every vehicle and building. In 1980, Houston was described as the "most air-conditioned place on earth". Officially, the hottest temperature ever recorded in Houston is 109 F (43 C), which was reached both on September 4, 2000 and August 28, 2011.
What weather factor produces a higher heat index?
The answer is the following: humidity

Problem: The North Slope is mostly tundra peppered with small villages. The area is known for its massive reserves of crude oil, and contains both the National Petroleum ReserveAlaska and the Prudhoe Bay Oil Field. Barrow, the northernmost city in the United States, is located here. The Northwest Arctic area, anchored by Kotzebue and also containing the Kobuk River valley, is often regarded as being part of this region. However, the respective Inupiat of the North Slope and of the Northwest Arctic seldom consider themselves to be one people.
What resource is the North Slope known for?
The answer is the following: massive reserves of crude oil

Problem: Network effects are a large factor with electrification. When converting lines to electric, the connections with other lines must be considered. Some electrifications have subsequently been removed because of the through traffic to non-electrified lines. If through traffic is to have any benefit, time consuming engine switches must occur to make such connections or expensive dual mode engines must be used. This is mostly an issue for long distance trips, but many lines come to be dominated by through traffic from long-haul freight trains (usually running coal, ore, or containers to or from ports). In theory, these trains could enjoy dramatic savings through electrification, but it can be too costly to extend electrification to isolated areas, and unless an entire network is electrified, companies often find that they need to continue use of diesel trains even if sections are electrified. The increasing demand for container traffic which is more efficient when utilizing the double-stack car also has network effect issues with existing electrifications due to insufficient clearance of overhead electrical lines for these trains, but electrification can be built or modified to have sufficient clearance, at additional cost.
What is a major factor whn it comes to electrification?
The answer is the following: Network effects

Problem: Rendering software which cannot process a Unicode character appropriately often displays it as an open rectangle, or the Unicode "replacement character" (U+FFFD, ), to indicate the position of the unrecognized character. Some systems have made attempts to provide more information about such characters. The Apple's Last Resort font will display a substitute glyph indicating the Unicode range of the character, and the SIL International's Unicode Fallback font will display a box showing the hexadecimal scalar value of the character.
What does SIL's Unicode Fallback font display when it can't display a character properly?
The answer is the following:
a box showing the hexadecimal scalar value of the character
