Updated: Crowdmapping Ielts Reading Answers

As fresh food stores leave a neighborhood, residents find it harder to eat well and stay healthy. Food deserts are linked with lower local health outcomes, and they may be a driving force in the health disparities between lower-income and affluent people in the US. Until recently, the issue attracted little national attention and received no ongoing funding for research. Now, more US cities are becoming aware of their food landscapes.

Over the last few months, a survey has been carried out of over 200 greengrocers and convenience stores in Crown Heights, a neighborhood in Brooklyn, New York. As researchers from the Brooklyn Food Association enter the details, colorful dots appear on their online map, which displays the specific of each of the food stores in a handful of central Brooklyn neighborhoods. Clicking on a dot will show you the store's name and whether it carries fresh fruit and vegetables, wholegrain bread, low-fat dairy, and other healthy options. The researchers plan eventually to survey the entire borough of Brooklyn.

The questions rarely use the same words as the text. For example, "increasing rapidly" in the question often matches "escalating" in the text. crowdmapping ielts reading answers updated

Despite its undeniable utility, crowdmapping faces significant scrutiny from academics and traditional cartographers. The foremost criticism pertains to data veracity. Because the information is contributed by the public, it is highly susceptible to misinformation, exaggeration, or deliberate manipulation. If a malicious actor falsely reports a roadblock or a supply shortage, emergency resources might be misallocated. To combat this, modern crowdmapping organizations employ sophisticated algorithmic filtering and community moderation to cross-reference and validate incoming data streams. Paragraph E

According to recent studies, people at higher risk of chronic disease and who receive minimal for the work they do frequently live in neighborhoods located in food deserts. But how did these food deserts arise? Linda Alwitt and Thomas Donley, marketing researchers at DePaul University in Chicago, found that supermarkets often cannot afford the amount of land required for their stores in cities. City planning researcher Cliff Guy and colleagues at the University of Leeds in the UK found in 2004 that smaller urban groceries tend to close due to competition from suburban supermarkets.

Paragraph E is entirely dedicated to criticisms. It mentions that "the risk of misinformation... is inherently high" and discusses "participation bias" which can skew data due to technological disparities. 4. Answer: A As fresh food stores leave a neighborhood, residents

(Note: The exact question order depends on your specific test paper, but these are the standard facts tested.)

Crowdmapping is a subtype of crowdsourcing that combines social media, mobile technology, and geographic information systems (GIS). It allows individuals to contribute real-time data to a shared map, often using their smartphones. Unlike static maps, crowdmapped platforms are dynamic, updating as quickly as users can upload information.
