You are tasked to use the Language Detection feature of Text Analytics in Azure. You provide the JSON inputs and receive two outputs, as given in code snippets below. The first output (Output 1) provides a confidence score of 1, whereas the second output (Output 2) returns a confidence score of 0. 
Review the scenario given above and complete the following code snippets. (Choose two options) 
Output 1: 
<pre>"documents":[
{
"detectedLanguage":{
"confidenceScore":1.0,
"iso6391Name":"fr",
"name":"......................................"
},
"id":"1",
"warnings":[
]
}
]
</pre>
Output 2: 
<pre>"documents":[
{
"detectedLanguage":{
"confidenceScore":0.0,
"iso6391Name":"(Unknown)",
"name":"..................................."
},
"id":"1",
"warnings":[ 
]
}
]
</pre> 

Answer options:

A.fr
B.French
C.countryHint
D.(Unknown)

Correct Answers: B and D
Option A is incorrect because fr is iso code for the french language. The name of the language is French.
Option B is correct. Since the confidence score for iso code “fr” is 1, the French language is returned as the name. Here is the completed code for Output 1.
<pre>"documents":[
{
"detectedLanguage":{
"confidenceScore":1.0,
"iso6391Name":"fr",
"name":"French"
},
"id":"1",
"warnings":[]
}
]
</pre>
Option C is incorrect because countryHint provides the hint for a region or country in case of an ambiguity in the language or if there are mixed languages in a sentence.
Option D is correct. Since the confidence score is 0, language is unknown. Here is the completed code for Output 2.
<pre>"documents":[
{
"detectedLanguage":{
"confidenceScore":0.0,
"iso6391Name":"(Unknown)",
"name":"(Unknown)"
},
"id":"1",
"warnings":[]
}
]
</pre>
