If a user agent reads a document with no character encoding information, it can fall back to using some other information.

If the user pressed keys 1 + 2 = 3 simultaneously the letter " c " appeared.

If a user added more than one drive to a system the user had to open the case and cut a trace in the circuit board to permanently change the drive's number, or hand-wire an external switch to allow it to be changed externally.

If the disk was not otherwise prepared with a custom format, ( e. g. for data disks ), 664 blocks would be free after formatting, giving 664 × 254 = 168, 656 bytes ( or almost 165 kB ) for user data.

If the user is unable to identify what is being demonstrated in a reasonable fashion, the map may be regarded as useless.

If the user wanted to keep his progress then the cartridge used had to have the same type of non-volatile memory hardware.

If it printed something then the tape and the printout were returned to the user, otherwise they were informed at which memory location it had stopped.

If the user decides to download the file, they negotiate the file transfer.

If the status code indicated a problem, the user agent might display the reason phrase to the user to provide further information about the nature of the problem.

If both channels were created at the same time, all user statuses are retained when the two are combined ; if one is newer than the other, special statuses are removed from those in the newer channel.

* If the library doesn't have information on a given topic, or if the library user wants more information, the librarian can refer the library user to another library or to an organization that can be contacted by phone or mail.

If the user opens the protective sliding door that covers the pins, the processor can be exposed to any electric charge the user has built up.

If the user has built up a substantial charge, the discharge can jump around the door's edge or pass through the door itself ( dielectric breakdown ).

If every user makes uploads then the servers would be flooded ; thus it is acceptable and often encouraged for users to just leech.

If there was not a market for natural gas near the wellhead it was virtually valueless since it had to be piped to the end user.

If an attacker gains access to such an internal password store, all passwords — and so all user accounts — will be compromised.

If the attacker finds a match, he knows that his guess is the actual password for the associated user.

If the password is carried as electrical signals on unsecured physical wiring between the user access point and the central system controlling the password database, it is subject to snooping by wiretapping methods.

If the user supplies a password matching the one stored for the supplied username, he or she is permitted further access into the computer system.

If the source code were included, it would be useful to a user, programmer, or system administrator, who may wish to modify the program or understand how it works.

If a bottle neck communication link offering data rate R is shared by " N " active users ( with at least one data packet in queue ), every user typically achieves a throughput of approximately R / N, if fair queuing best-effort communication is assumed.

If the man on the sidewalk is surprised at this question, it has served as an exclamation.

If there be a disinterested patriot in America, 'tis General Washington, and his bravery, none can question ''.

If it proclaims that the best is yet to be, it always arouses, at least in the young, either a suspicious question or perhaps the exclamation of the Negro youth who saw on a tombstone the inscription, `` I am not dead but sleeping ''.

If there were more such cases, it would be easier to answer the question whether the policy-makers favor their own social classes.

( One big question: If Colmer was to be purged, what should the House do about the other three senior Mississippians who supported the maverick electors??

`` If you substitute ' atom ' for ' angel ', the problem is not insoluble, given the metallic content of the pin in question ''.

If the second theory is correct, this raises the further question of why the Persians, having hesitated for several days, then attacked.

If so, the next question is whether the patient can respond in a meaningful way to questions and commands.

If one asks the question, " Why are there any contingent beings at all?

If a system in question has an impulse response of

A more specific question could be: " If someone else can make better out of his / her life than I can, is it then moral to sacrifice myself for them if needed?

If the species concerned were short-lived ( in geological terms, lasting a few hundred thousand years ), then it is certain that the sediments in question were deposited within that narrow time period.

If the governor withholds the Queen's assent, the sovereign may within two years disallow the bill, thereby annulling the law in question.

Islamists have asked the question, " If Islam is a way of life, how can we say that those who want to live by its principles in legal, social, political, economic, and political spheres of life are not Muslims, but Islamists and believe in Islamism, not Islam?

If A attempts to support his position with an argument that shows that the law ought to allow him to do the thing in question, then he is guilty of ignoratio elenchi.

If the suspect responds " no " to the first question, the officer is required to re-read the Miranda warning, while saying " no " to the second question invokes the right at that moment ; in either case the interviewing officer or officers cannot question the suspect until the rights are waived.

If truth is understood according to correspondence theory, the question of the truth or falsity of sentences not contingent upon external phenomena cannot be tested ( see tautologies ).

If the first-countability axiom were imposed on the topological spaces in question, the two above conditions would be equivalent.

If there is, such as in some denominations of Wicca, it is a particular of the denomination in question, and not a universal practice.

If the objects are indeterminate until one of them is measured, then the question becomes, " How can one account for something that was at one point indefinite with regard to its spin ( or whatever is in this case the subject of investigation ) suddenly becoming definite in that regard even though no physical interaction with the second object occurred, and, if the two objects are sufficiently far separated, could not even have had the time needed for such an interaction to proceed from the first to the second object?

If they had any significant level of non-organic parts then something as simple as an x-ray scan would show them not to be human ( unless their creators designed the non-organic parts to have almost exactly the same structure and density as the organic components they were replacing, which would be both infeasible and highly improbable but not completely out of the question ).

This is because each point on the supply curve is the answer to the question " If this firm is faced with this potential price, how much output will it be able to and willing to sell?

" If a firm has market power, so its decision of how much output to provide to the market influences the market price, then the firm is not " faced with " any price, and the question is meaningless.
