 A violation of this rule occurs when a clause within a query expression does not begin on the same line as the previous clause, or on the line after the query clause. For example:
 ```c#
-    object x = select a in b
+    object x = from num in numbers
 
-        from c;
+        select num;
 ```
 
 The query clause can correctly be written as:
 ```c#
-    object x = select a in b from c;
+    object x = from num in numbers select num;
 ```
 or:
 ```c#
     object x =
-        select a
-        in b
-        from c;
+        from num
+        in numbers
+        select num;
