+## 这个表达式的结果是什么?
+```go

+```
+
+1. "Hello" "World"
+2. "Hello" \"World\" *CORRECT*
+3. "Hello" `"World"`
+4. "\"Hello\" `\"World\"`"
+
+> **1:** Go doesn't interpret the escape sequences in raw string literals.
+>
+> **2:** That's right. Go interprets `\"` as `"` but it doesn't do so for ` \"World\"`.
+>
+
+
+## What's the best way to represent the following text in the code?
+```xml
+<xml>
+  <items>
+    <item>"Teddy Bear"</item>
+  </items>
+</xml>
+```
+
+1. *CORRECT*
+```go
+`<xml>
+    <items>
+        <item>"Teddy Bear"</item>
+    </items>
+</xml>`
+```
+
+2.

+    <items>
+        <item>\"Teddy Bear\"</item>
+    </items>

+```
+
+> **2-3:** You can't write a string literal like that. It can't be multiple-lines.
+>
+> **4:** You don't need to use escape sequences inside raw string literals.
+>
+
+
+## What's the result of the following expression?
+```go
+len("lovely")
+```
+
+1. 7
+2. 8
+3. 6 *CORRECT*
+4. 0
+
+> **2:** Remember! "a" is 1 char. `a` is also 1 char.
+>
+
+
+## What's the result of the following expression?
+```go
+len("very") + len(`\"cool\"`)
+```
+
+1. 8
+2. 12 *CORRECT*
+3. 16
+4. 10
+
+> **1:** There are also double-quotes, count them as well.
+>
+> **2:** That's right. Go doesn't interpreted \" in raw string literals.
+>
+> **3:** Remember! "very" is 4 characters. `very` is also 4 characters.
+>
+> **4:** Remember! Go doesn't interpreted \" in raw string literals.

+
+
+## What's the result of the following expression?
+```go

+
+> **1:** There are also double-quotes, count them as well.
+>
+> **2:** Remember! Go interprets escape sequences in string literals.
+>
+> **4:** That's right. Go does interpret \" in a string literal. So, "\"" means ", which is 1 character.
+>
+
+
+## What's the result of the following expression?
+```go
+len("péripatéticien")
+```
+
+**HINT:** é is 2 bytes long. And, the len function counts the bytes not the letters.
+
+**USELESS INFORMATION:** "péripatéticien" means "wanderer".
+
+1. 14
+2. 16 *CORRECT*
+3. 18
+4. 20
+
+> **1:** Remember! é is 2 bytes long.
+>
+> **2:** An english letter is 1 byte long. However, é is 2 bytes long. So, that makes up 16 bytes. Cool.
+>
+> **3:** You didn't count the double-quotes, did you?
+>
+
+
+## How can you find the correct length of the characters in this string literal?
+```go
+"péripatéticien"
+```
+
+1. `len(péripatéticien)`
+2. `len("péripatéticien")`
+3. `utf8.RuneCountInString("péripatéticien")` *CORRECT*
+4. `unicode/utf8.RuneCountInString("péripatéticien")`
+
+> **1:** Where are the double-quotes?
+>
+> **2:** This only finds the bytes in a string value.
+>
+> **4:** You're close. But, the package's name is utf8 not unicode/utf8.
+>
+
+
+## What's the result of the following expression?
+```go
+utf8.RuneCountInString("péripatéticien")
+```
+
+1. 16
+2. 14 *CORRECT*
+3. 18
+4. 20
+
+> **1:** This is its byte count. `RuneCountInString` counts the runes (codepoints) not the bytes.
+>
+> **2:** That's right. `RuneCountInString` returns the number of runes (codepoints) in a string value.
+>
+
+
+## Which package contains string manipulation functions?
+1. string
+2. unicode/utf8
+3. strings *CORRECT*
+4. unicode/strings
+
+
+## 这个表达式的结果是什么?
+```go
+strings.Repeat("*x", 3) + "*"
+```
+
+**HINT:** Repeat function repeats the given string.
+
+1. `*x*x*x`
+2. `x*x*x`
+3. `*x3`
+4. `*x*x*x*` *CORRECT*
+
+> **1:** You're close but you missed the concatenation at the end.
+>
+> **2:** Look closely.
+>
+> **3:** Wow! You should really watch the lectures again. Sorry.
+>
+> **4:** That's right. Repeat function repeats the given string. And, the concatenation operator combines the strings.
+>
+
+
+## 这个表达式的结果是什么?
+```go
+strings.ToUpper("bye bye ") + "see you!"
+```
+
+1. `bye bye see you!`
+2. `BYE BYE SEE YOU!`
+3. `bye bye + see you!`
+4. `BYE BYE see you!` *CORRECT*
+
+> **1:** You missed the ToUpper?
+>
+> **2:** You're close but look closely. ToUpper only changes the first part of the string there.
+>
+> **3:** Not even close. Sorry.
+>
+> **4:** Perfect! Good catch! ToUpper only changes the first part of the string there.
+>
