• A gravel mulch pathway leading to the entrance
• Concrete plinth surrounding a building foundation
• A green roof with growing media and vegetation (Correct answer)
• A decorative fence around the building perimeter

Correct answer: A green roof with growing media and vegetation

Green roofs absorb and retain rainfall in their growing media and through plant evapotranspiration, significantly reducing the volume of stormwater runoff from building rooftops.

Question 79: A 'riparian buffer' in site planning primarily functions to:

• Provide pedestrian access along waterways
• Filter pollutants and stabilize streambanks between developed land and a water body (Correct answer)
• Store stormwater runoff during peak rainfall events
• Define the 100-year floodplain boundary

Correct answer: Filter pollutants and stabilize streambanks between developed land and a water body

Riparian buffers are vegetated strips along waterways that intercept runoff, filter pollutants, reduce erosion, and protect aquatic habitat.

Question 80: This process chooses the best site use and development.

• Site Selection Process
• Site Analysis
• Development Sustainability Process (Correct answer)
• Site Planning

Correct answer: Development Sustainability Process

The Development Sustainability Process involves evaluating potential sites and their uses to ensure long-term environmental, social, and economic viability. It aims to select and plan development that meets current needs without compromising the ability of future generations to meet their own needs, making it the process for choosing the 'best' site use and development from a holistic perspective.

Question 81: Which soil amendment is commonly used to improve drainage in heavy clay soils?

• Vermiculite
• Compost
• Peat moss
• Coarse sand or grit (Correct answer)

Correct answer: Coarse sand or grit

Coarse sand or grit added to clay soils increases pore space, improving drainage and aeration.

Question 82: Using water temperature as an example

• an abiotic factor. (Correct answer)
• a biotic factor.

Correct answer: an abiotic factor.

Abiotic factors are the non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Water temperature is a physical characteristic of the environment, not a living component. Therefore, it is classified as an abiotic factor because it is a non-biological influence on an ecosystem.

Question 83: When calculating floor area ratio (FAR), which of the following is correct?

• FAR = gross building area ÷ number of parking spaces
• FAR = total floor area of all building stories ÷ total lot area (Correct answer)
• FAR = number of floors × lot coverage percentage
• FAR = building footprint ÷ total lot area × 100%

Correct answer: FAR = total floor area of all building stories ÷ total lot area

FAR is computed by dividing the total gross floor area of all stories by the area of the parcel, expressing how much building mass is allowed relative to lot size.

Question 84: Energy rises in an energy pyramid.

• decreases (Correct answer)
• stays the same
• increases exponentially
• increases

Correct answer: decreases

An energy pyramid illustrates the flow of energy through different trophic levels in an ecosystem. As you move up the pyramid from producers to higher-level consumers, the amount of available energy significantly decreases. This is due to the loss of energy (primarily as heat) at each transfer between trophic levels, following the 10% rule.

Question 85: Which concept, popularized by landscape urbanist Charles Waldheim, describes the use of landscape as the primary infrastructure for organizing contemporary cities?

• Ecological Urbanism
• Smart Growth
• New Urbanism
• Landscape Urbanism (Correct answer)

Correct answer: Landscape Urbanism

Landscape Urbanism, associated with Charles Waldheim and others, positions landscape — rather than architecture — as the primary medium for organizing and structuring the contemporary city.

Question 86: Which nutrient deficiency typically causes yellowing of leaves (chlorosis) in plants?

• Calcium
• Iron or Nitrogen (Correct answer)
• Phosphorus
• Potassium

Correct answer: Iron or Nitrogen

Chlorosis (yellowing) is most commonly caused by iron or nitrogen deficiency, as both are essential for chlorophyll production.

Question 87: Frederick Law Olmsted's 'Emerald Necklace' park system is located in which US city?

• Boston (Correct answer)
• Chicago
• Philadelphia
• New York City

Correct answer: Boston

The Emerald Necklace is a chain of parks and parkways in Boston, Massachusetts, designed by Olmsted connecting Franklin Park to the Boston Common.

Question 88: "Landscape design is steady change. <br>It refers to composition's three-dimensional perspective.<br> To make landscape viewing easier, it gradually alters element patterns.<br>It gradually changes style in a sensible order.<br> Planned color, plant, and accessory changes will blend better."

• Focalization
• Form
• Transition (Correct answer)
• Repetition

Correct answer: Transition

The text repeatedly emphasizes 'gradually alters element patterns,' 'gradually changes style in a sensible order,' and 'steady change' to make viewing easier and blend elements. This concept is known as transition in landscape design, where elements are arranged to create a smooth, flowing progression from one area or characteristic to another, guiding the eye and creating harmony.

Question 89: What was the primary design philosophy behind the City Beautiful movement in early 20th-century American urban design?

• Industrial efficiency and grid planning
• Civic grandeur through monumental civic spaces, parks, and boulevards (Correct answer)
• Automobile-oriented suburbs
• High-density housing reform

Correct answer: Civic grandeur through monumental civic spaces, parks, and boulevards

The City Beautiful movement promoted civic improvement through formal, monumental design including grand boulevards, parks, and civic plazas to inspire civic pride.

Question 90: What is the primary driver of primary succession on a newly formed volcanic island?

• Runoff from adjacent land masses
• Animal migration bringing plant seeds
• Wind-dispersed seeds and spores colonizing bare substrate (Correct answer)
• Underwater seed banks activating

Correct answer: Wind-dispersed seeds and spores colonizing bare substrate

Primary succession begins with pioneer organisms like lichens and wind-dispersed seeds colonizing bare, lifeless substrate with no existing soil.

Question 91: In landscape grading, a 'swale' is designed to:

• Retain water on site indefinitely
• Convey surface runoff in a controlled direction away from structures (Correct answer)
• Mark property boundaries with low plantings
• Create raised planting areas above grade

Correct answer: Convey surface runoff in a controlled direction away from structures

A swale is a shallow, vegetated channel designed to collect and direct stormwater runoff across a landscape while reducing velocity and promoting infiltration.

Question 92: ________ are imaginary lines that join points of equal elevation on the land surface above or below a reference surface like the mean sea level.

• Map
• Contours (Correct answer)
• Topography
• None of these
• Slope

Correct answer: Contours

'Contours' are imaginary lines on a map that connect points of equal elevation above or below a reference surface, such as mean sea level. They are fundamental tools in topography for visualizing the shape, steepness, and elevation of the land. Slope refers to the gradient, and topography is the overall study of landforms.

Question 93: Which term describes a plant that completes its life cycle within a single growing season?

• Ephemeral
• Annual (Correct answer)
• Biennial
• Perennial

Correct answer: Annual

An annual plant germinates, flowers, sets seed, and dies all within one growing season, unlike perennials that live for multiple years.

Question 94: The shrew powers what?

• cricket
• frog
• grasshopper
• snake (Correct answer)

Correct answer: snake

In many ecosystems, shrews are small mammals that feed on insects and other invertebrates. Snakes are often predators of small mammals, including shrews. Therefore, the energy stored in a shrew would be transferred to a snake if the snake consumes the shrew, representing a trophic link.

Question 95: Which ecological concept describes the edge zone where two different plant communities meet, often exhibiting higher biodiversity than either adjacent community?

• Climax community
• Ecotone (Correct answer)
• Monoculture
• Canopy closure

Correct answer: Ecotone

An ecotone is the transitional zone between two distinct ecosystems or plant communities, where species from both communities and unique edge species coexist, typically increasing biodiversity.

Question 96: During the City Beautiful era, these architects created Brasilia, the new capital of Brazil:

• Lucio Costa (Correct answer)
• Walter Griffin
• Edward Lutyens
• Alber t Meyer

Correct answer: Lucio Costa

Lucio Costa was the urban planner who won the competition to design Brasília, the new capital of Brazil, in the late 1950s. His master plan, often described as resembling an airplane, laid out the city's monumental axes and functional zones. While Oscar Niemeyer designed many of its iconic buildings, Costa was responsible for the overarching urban design that embodied principles of modernism and grand civic planning.

Question 97: The intermediate disturbance hypothesis predicts that species diversity is highest when:

• Disturbance is completely absent for long periods
• Only two dominant species compete
• Disturbance occurs at intermediate frequency and intensity (Correct answer)
• Disturbance frequency is very high and intense

Correct answer: Disturbance occurs at intermediate frequency and intensity

The intermediate disturbance hypothesis states that moderate disturbance levels prevent competitive exclusion while allowing recovery, maximizing species diversity.

Question 98: For swiftly and consistently drawing shapes, plastic templates are utilized.

• Themes
