1.What are the basic concepts of the Wahhabi movement?

In addition to promoting a strict devotion to the Quran and hadith, this movement also promoted the use of ijtihad. As a result of this agreement, Muhammad bin Saud, a local leader, agreed to accept political subordination in exchange for the protection and propagation of the Wahhabi movement.

2.What event caused the founding of Hizbollah?

Following Israel's invasion of Lebanon in 1982, the concept of Hezbollah originated among Lebanese clerics who had studied in Najaf and had accepted the model established by Ayatollah Khomeini following the Iranian Revolution in 1979. The organization was founded as part of an Iranian effort, which included funding and the dispatch of a core group of Islamic Revolutionary Guard Corps (pasdaran) instructors, to unite a number of Lebanese Shia groups in order to resist Israeli occupation[35][36][9] and improve the standing and status of the country's long marginalized and underrepresented Shia community.

Step-by-step explanation

3.What are the benefits of homegrown terrorists for terrorist groups?

Foreign terrorist organizations (FTOs) continue to use domestic terrorists to plan against the United States, and the Department's duty of preventing another attack from abroad is carried out on a daily basis. 
Regrettably, the severity and frequency of domestic threats have also increased. The ideas and messages of FTOs impact homegrown violent extremists (HVEs). 
There has been an alarming increase in attacks by individuals motivated by a variety of domestic terrorist ideologies6, including racially and ethnically motivated violent extremism, including white supremacist violent extremism, anti-government and anti-authority violent extremism, and other ideological strains that drive terrorist violence. Hate crimes and non-ideologically motivated large-scale or disproportionately lethal acts of mass violence, like as mass attacks, complete the picture of terrorism and targeted violence plaguing the Homeland.

4.What are some clues about a possible suspicious package or envelope to look for?

Suspicious packages may have limited endorsements such as "personal" or "private." When the addressee does not regularly receive personal mail at the office, this is critical.
The addressee's name and/or title may be incorrect.
Suspicious shipments or articles may have distorted handwriting, or the name and address may have been created using homemade labels or cut-and-paste letters.
Suspicious goods or articles may include protruding wires, visible aluminum foil or oil stains, and may exude an unusual odor.
Suspicious parcels or articles may have an unusually large amount of postage.
Letter bombs may have a stiff feel to them, as well as an uneven or lopsided appearance.
Suspicious parcels or goods may be unprofessionally wrapped with a variety of tape combinations to secure the package and may be labeled "Fragile-Handle With Care" or "Rush-Do Not Delay."
Packages or goods that are suspicious may have an unusual shape, soft patches, or bulges.
Suspicious packages or articles may emit a buzzing, ticking, or sloshing noise.
When extracting things from an envelope or parcel, you may feel pressure or resistance.
