An engineer configures a prefix list (fred) on R1 that permits only 2.0.0.0/8 and then enables the filter with the neighbor R2 prefix- list fred out command. Upon exiting configuration mode, the engineer uses some show commands on R1, but no other commands.Which of the following is true in this case?()
A. The show ip bgp neighbor 2 .2.2.2 received -routes command lists the three original prefixes.
B. The show ip bgp neighbor 2.2.2.2 advertised - routes command lists the three original prefixes.
C. The show ip bgp neighbor 2.2.2.2 routes command lists the three original prefixes.
D. T he show ip bgp neighbor 2.2.2.2 routes command lists only 2.0.0.0/8.
E. The show ip bgp neighbor 2.2.2.2 advertised - routes command lists only 2.0.0.0/8.

Viewed from a star in some other comer of the galaxy, Earth would be a speck, a faint blue dot hidden in the blazing light of our sun. While our neighbors Venus and Mars would reflect a fairly even glow, Earth would put on a little show. Earth's light would brighten and dim as it spins, because oceans, deserts, forests and clouds—which are all too small to be seen from such a distance-reflect varying amounts of sunlight. The variations, it turns out, are so strong and distinctive that surprising amount of information could be taken from a simple ebb and flow of light. Scientists at Princeton University and the Institute for Advanced Study conducted a detailed study of Earth's reflections as a way for human scientists to learn about distant planets that may be like our own.
(2) "If you looked at our solar system from far away, and you looked at the terrestrial planets--Mercury, Venus, Earth and Mars--one of the quickest ways to see that Earth is unique is by looking at the light curve," said Ed Turner, professor of astrophysics and a co-author of the study. "Earth has by far the most complicated light curve." The standard thinking in the field had been that most of the information about an Earth-like planet would come from spectral analysis, a static reading of the relative component of different colors within the light, rather than a reading of changes over time. Spectral analysis would reveal the presence of gases such as water vapor, carbon dioxide and oxygen, in the planet's atmosphere, looking at the change in light over time docs not replace spectral analysis, but it could greatly increase the amount of information scientists could learn, said Turner. It may indicate, for example, the presence of weather, oceans, ice or even plant life.
"Earth would put on a little show" means: as it spins, ______.
A.Earth is a more active planet than Venus and Mars
B.Earth reflects a brighter light curve than Venus and Mars
C.Earth shows oceans, deserts, forests and clouds, while Venus and Mars don't
D.Earth reflects sunlight in an ebb-and-flow manner

听力原文: As you probably know, log structures are gaining popularity. They are no longer just the simple country homes that we think of as the traditional log cabin. Some upscale homes now incorporate natural round logs in sealing beams and walls. People seem to think that the rounded logs give their homes a cozy warm atmosphere. And even people who want to build a traditional log cabin on their own can buy a kit with precut logs that fit together like pieces of lig-saw puzzle. Before showing you some slides of modem log houses, I'd like to give you a little historical background on the subject.
Log cabins were first built in the late 1600s along the Delaware river valley. The European immigrants who settled there brought centuries' old traditions of working with logs. And in this heavily wooded area logs were the material in hand. Log cabins were the most popular in the early 1800s with the settlers who were moving west. They provided the answer to the pioneer's need for a sale and sliding boards for windows. But the log buildings that have probably had most influence on modern architects are those of the mountain retreats of wealthy New Yorkers. These country houses which were popular in the early 1900s typify what's known as the Adoroundyx style. Now let's look at those slides.
What is the speaker mainly discussing?
A.Traditional European architecture.
B.Techniques for building log cabins.
C.The history of log structures.
D.How to build a home by yourself.
