On the eastern side of the newly developed residential neighborhood, what change has occurred at the location where a tree now stands in the front yard of a house?

**A)** The tree was removed during construction.
**B)** The tree was newly planted.
**C)** The tree was pruned to clear the sidewalk.
**D)** The tree was relocated from the backyard.

B

Looking at the first image, the area is an undeveloped plot of land consisting mostly of dirt, tire tracks, and sparse vegetation, with no houses or structured landscaping present. Moving to the second image, a residential neighborhood has been constructed on this site, featuring several houses with paved roads and sidewalks. Focusing on the eastern side of this new development, I can see individual homes with manicured lawns. In the front yard of one of these houses, there is a distinct, small green tree that was not present in the original image of the empty lot. Since the entire residential area, including the houses and the landscaping, is new, the presence of this tree in a previously empty field indicates that it was newly planted as part of the home's landscaping.

Has a small section of sidewalk been constructed on the western edge of the residential block, connecting to the existing path along the street?

Yes

Looking at the first image, the western edge of the residential block, adjacent to the road, shows a gap in the paved surface where the grass and dirt meet the street. In the second image, comparing the same area, a light-colored, narrow strip of concrete has appeared, filling in that gap and creating a continuous sidewalk that connects the residential properties to the existing path along the street. This new addition is clearly visible as a bright, linear feature that was absent in the initial image.

In the southwest corner of the area shown, what change occurred regarding the swimming pool?

**A)** A swimming pool was demolished.
**B)** A swimming pool was newly constructed.
**C)** An existing swimming pool was enlarged.
**D)** A swimming pool was converted into a garden plot.

B

Looking at the first image, the southwest corner of the area consists of undeveloped land with rough terrain, dirt, and sparse vegetation, showing no signs of residential structures or amenities. When I shift my gaze to the second image, the entire area has been developed into a residential neighborhood with houses and paved roads. Specifically focusing on the southwest corner, I can see a house has been built, and right next to it, there is now a distinct, bright blue oval shape that is clearly a swimming pool. Since this feature was completely absent in the first image and is now present in the second, it is evident that a swimming pool was newly constructed.

In the northern portion of the images, near the edge of the residential development, what change occurred regarding the sidewalk?

**A)** It was demolished and replaced with a dirt path.
**B)** It was newly constructed on previously forested land.
**C)** It was widened to accommodate more foot traffic.
**D)** It was removed to allow for the planting of new trees.

B

Looking at the first image, the entire area is dominated by dense forest cover with only a narrow, unpaved dirt trail cutting through the trees on the right side. Moving to the second image, there is a dramatic transformation where a residential neighborhood has been built. In the northern portion, where the forest once stood, a paved road and accompanying sidewalk have been installed. Comparing the two, the area that was previously just trees and a dirt path now features a structured, light-colored paved sidewalk running alongside the new street, indicating that it was newly constructed on land that was previously forested.

What change occurred to the sidewalk located along the vertical road in the upper right corner of the image?

**A)** It was narrowed to accommodate a wider road shoulder.
**B)** It was extended to form a continuous walkway along the street.
**C)** It was removed and replaced with a grassy median.
**D)** It was repaved with a dark asphalt material.

B

Looking at the upper right corner of the first image, I see a vertical road where the sidewalk is fragmented, appearing as short, disconnected white segments. When I shift my gaze to the second image, I notice that these gaps have been filled in. The white line representing the sidewalk now runs continuously along the edge of the road, connecting the previously separate sections into one long, unbroken walkway. There is no evidence of narrowing, removal, or a change in material to asphalt; instead, the primary change is the completion of the path, indicating that the sidewalk was extended to form a continuous walkway along the street.

What change can be observed regarding the building located in the lower-left section of the image, situated just to the east of the main north-south road?

**A)** The original building was demolished and replaced by a larger, more modern residence.
**B)** The building was converted into a paved parking lot for the surrounding neighborhood.
**C)** A large swimming pool was installed in the backyard of the original house.
**D)** The building was replaced with a small community playground and park area.

A

Looking at the first image, in the lower-left area just east of the main north-south road, there is a relatively small, simple rectangular building with a light-colored roof. Moving to the second image, I notice that this specific small structure is gone. In its place, there is now a significantly larger building with a more complex roofline and a darker color, which appears to be a more modern and substantial residence. The surrounding yard has also been modified to accommodate this larger footprint, confirming that the original small building was demolished to make way for a larger home.

Has a new building been constructed on the previously empty lot in the southeastern portion of the residential area?

Yes

Looking at the first image, the southeastern portion of the residential area, specifically the land between the diagonal road and the bottom edge of the frame, consists of several empty, grassy lots. In the second image, I can see that this same area has undergone significant development. Multiple new houses with dark grey roofs have been constructed on those previously vacant lots, and driveways have been paved, with several cars now parked in front of these new residences. The contrast between the open green space in the first image and the dense housing in the second clearly indicates that new buildings have been constructed.

In the southern section of the residential neighborhood, adjacent to the dense tree line at the end of the cul-de-sac, has a new building with a complex, dark-colored roof been constructed where there was previously undeveloped land?

Yes

Looking at the first image, the entire area is covered in dense, natural vegetation and trees, with no signs of human development or structures. Moving to the second image, a residential neighborhood has been built over this land. Specifically, in the southern section near the bottom of the frame, right where the developed area meets the remaining dense tree line, there is now a large house. This building features a complex, dark-colored roof with multiple gables and ridges, situated just past the end of the cul-de-sac. Comparing this to the first image, this specific spot was previously just undeveloped forest, confirming that a new building has been constructed there.

What change can be observed regarding the paved road in the area north of the main highway?

**A)** A new paved road has been constructed.
**B)** The paved road was demolished and replaced with vegetation.
**C)** The paved road was narrowed to a single lane.
**D)** No change has occurred to the paved road in this location.

A

Looking at the first image, there is a main highway running across the bottom, and the area immediately north of it consists of a grassy median and a large patch of undeveloped, vegetated land. There is no paved road visible between the main highway and the dense forest further north. Moving to the second image, while the main highway remains, a new, wide paved road has been constructed running parallel to it, cutting through the area that was previously just vegetation. This new road is clearly visible as a light-gray strip of asphalt separating the main highway from the forested area, indicating that a new paved road has been added to the landscape.

Has a new residential building been constructed in the southern section of the area, specifically positioned as the second house from the left in the bottom row of homes?

Yes

Looking at the first image, the entire area is an undeveloped, open field with a rough, brownish-grey texture and no structures present. When I shift my gaze to the second image, the landscape has been completely transformed into a residential neighborhood. I can see a street layout with several houses now built. Focusing on the southern section of the development, there is a bottom row of homes. Counting from the left, the first house is clearly visible, and immediately to its right, there is a second house. Comparing this specific spot to the first image, where there was only empty land, it is evident that this second house from the left in the bottom row has been newly constructed.
