In this step, we will apply the argument evaluation framework proposed by Johnson and Blair (1994) which includes the following criteria:

Sufficiency: An argument complies with the sufficiency criterion if its premises provide enough evidence for accepting or rejecting the claim.

An argument is a good one, if the reasons are sufficient for believing the claim to be true. However, there are arguments which infer a very general claim from one example only. The classical example is the following argument “My neighbor has an academic degree and is the mayor of our town. Therefore, all mayors have an academic degree”. The very general claim is inferred from only one sample/instance. So the reason given as evidence is not sufficient for arriving at the very general claim that all mayors have an academic degree.
The following examples illustrate this flaw in real arguments:

Prompt: “International tourism is now more common than ever before. Some feel that this is a positive trend, while others do not. What are your opinions on this?” Claim: “It has contributed to the economic development as well as preserved the culture and environment of the tourist destinations”

Example 1:
Argumentative Text: “International tourism promotes many aspects of the destination country's economy in order to serve various demands of tourists. Take Cambodia for example, a large number of visitors coming to visit the Angkowat ancient temple need services like restaurants, hotels, souvenir shops and other stores. These demands trigger related business in the surrounding settings which in turn create many jobs for local people improve infrastructure and living standard. Therefore tourism has clearly improved lives in the tourist country.”

The claim of the argument is present in the last sentence of the paragraph. It states that “tourism has improved life in the tourist country (economically)”. As reason the author cites one example which shows this improvement. However, only one example is not sufficient for inferring the general claim of the argument.

Example 2:
Argumentative Text: “Through tourism industry, many cultural values have been preserved and natural environments have been protected. For instance, in Vietnam, many cultural costumes and natural scenes, namely ‘Trong Dong’ drum performance and ‘Ha Long’ bay, are being encouraged to preserve and funded by the tourism ministry. Without this support and profit from tourism, many traditional cultures would disappear due to its low income works. Thus, tourism has survived many non-tangible cultural values and beauty scenes.”

In support of the claim the author cites a single example from Vietnam which is not sufficient to infer this very general claim.

Example 3:
Argumentative Text: "Tourism has clearly contributed to both economic development and the preservation of culture and environment in many destinations. According to the World Travel & Tourism Council (WTTC), in 2019, tourism accounted for 10.4% of global GDP and supported over 334 million jobs worldwide, many of which were in developing countries. In Bhutan, for instance, tourism revenue is reinvested into conservation efforts, helping maintain its forests, which cover more than 70% of the country. Similarly, in Peru, the income from tourism at Machu Picchu has been used for the restoration and maintenance of Inca cultural heritage sites. These cases, backed by global data, show that tourism plays a substantial role in both economic growth and the protection of cultural and natural assets."

The author supports the claim with both statistical facts (e.g., tourism's share in global GDP and employment from WTTC) and multiple real-world examples from Bhutan and Peru. These facts and examples cover different regions and aspects (economic, cultural, and environmental), thus providing sufficient evidence for the general claim.

Next, you will be shown argumentative texts on the topic "TV vs. Books". Make sure to apply the guidelines on sufficiency for the assessment of these texts.
