Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Race conditions when accessing shared state
Global Interpreter Lock (GIL) limitations and race conditions on shared objects are common issues in Python multithreading.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Race conditions when accessing shared state
Why this is correct
Shared memory across threads often requires locking.
- ✓
The GIL prevents true parallelism for CPU-bound tasks
Why this is correct
The GIL is a known bottleneck for CPU-bound operations in threads.
- ✗
Threads always execute slower than single-threaded code
Why it's wrong here
They can improve I/O-bound performance significantly.
- ✗
Threads consume more memory than processes
Why it's wrong here
Threads are generally lighter than processes.
- ✗
Socket objects are automatically thread-safe
Why it's wrong here
Socket objects are not inherently thread-safe for shared operations.
